How to disable the SMP support in GRML
by Keith Hinton 27 Mar '07

27 Mar '07

I am trying to have a friend of mine with software speech on GRML have SMP shut off on his system. Why is this? Speechd-up and Speech-Dispatcher, have some issues with the threading support in SMP or something, that makes them crash at random, (and only when SMP) is used in the kernel. This bug has existed for a long time, and only some machines are effected while other similar dual-core processers are not. So far, we have tryed the following ordering of options: grml nosmp swspeak, grml swspeak nosmp, swspeak nosmp (without GRML) nosmp swspeak (Again without typing grml first) His box seems to boot fine if you only pass "GRML sswspeak" to it, but if he uses nosmp, the machine seems to freze at the loading of theLinux kernel. Is that chete code broken on GRML0.8 (The version being used)? Have there been any spisific issues that anyone has had with grml and the nosmp option? I could manually shut off SMP support in GRML's kernel, grab the kernel sources, disable SMP, try to figure out how to define "Broken_on_SMP=yes, or whatever, (wich would work fine) But I really do not wish to begin manually compiling the kernel. I can, you understand. But I find it an annoyance to have to spend time downloading the sources for 2.6.17-grml, turning off SMP support, (I am not eaven sure) if the kernel could be recompiled from the CD. Would that work, Mika? Or, would I, (most likely) encounter kernel compilation errors because the CD is being used. Would there eaven be enough space in the LiveCD environment (what get's loaded onto the system) to eaven extract the deb file? Or, would I encounter an error? Probably, I would. That is just my idea on that. Could anyone send me an email about these questions? I have asked multiple questions today, and need more then one answer. I know this started out as an "NoSMP" issue, but I need to also get my questions about the recompilation of the kernel in LivecCD mode being possible or not. I was going to have my friend do the following: rsync to get the deb file from my Gentoo Linux server, then do the following: DPKG -I linux-source-2.6.17-grml_grml.06_all.deb Then, assuming that worked, cd /usr/src/linux cp /boot/config-2.6.17-grml .config make oldconfig && make menuconfig Then finally: make && make modules_install Once the kernel is recompiled, coppy the changed config file back to the /boot folder, erase the deb file, install GRML to the hard-drive, and reboot. This would be better Mika then me making a deb file already, I'd just use the kernel sources long enough to recompile everything. What I am afraid of is that my wonderful idea will fail because I'll be trying to do all this on a running LiveCD. Could you kindly please try to get back to me with any information on the questions about nosmp and kernel compilation, CD-space (when the environment has been uncompressed from squashfs) into memory, etc?

Re: booting from external disk
by August C. Quint 23 Mar '07

Hi, and thanks Michael for your reply. >> Maybe using Grub instead is worth a try. I think we should first try to solve problem #2. >> Sorry no idea yet. Can you please provide me a screenshot of the >> booting process where it hangs? Sorry, I don't know how to make a screenshot in this stage of booting. And I don't have a digital camera (yet). So I try to write down the lines visible: the last lines before the problem happesn are related to raidx, so here it goes: Success: loaded module raid456 Success: loaded module raid5 Success: loaded module raid6 Modprobe: FATAL: Module raid10 not found Done. Begin: Assemblying all MD arrays ... Now I get 6x the lines: usb 2-2: reset high speed USB device running ehci_hcd and address 2 followed by sd: 0:0:0:0: SCSI error: return code = 0x00050000 And this will continue. It looks like it accessed the disk successfully but it tries to access the single disk as a raid-disk in this stage (but I'm no expert here). What can I do? Which information do you need? >> Oh, and you might want to try to use root=UUID=... instead of >> root=/dev/sd[a-z]... so you can make sure your system uses the >> correct device for booting. where do I have to put these modifications (I'm no expert here) ? I guess: I can use Knoppix to boot the machine and look for the file lio.conf (or so) on this external harddisk. Right? AugustQ

booting from external disk
by August C. Quint 22 Mar '07

22 Mar '07

Hi, I'm looing for a Linux-system that can boot from an USB-hard-disk. Via a Google I found Grml. But I have some problems with this. So please allow me to describe the system, the problems etc. My system: Aldi offered a notebook in may 2006 and I bought one. This is my system, if you need more information about it let me know. What I did: I downloaded the grml.iso-file via grml.gwendoline.at, burned a Cd and started the notebook: works, fine. I added my external hard-disk via USB ( I removed the internal hard-disk for safety, I want to keep the installed XP) and installed the software via grml2hd: works, fine. For a test I stopped the machine, removed the CD and started it again. In the BIOS I've checked 'boot from USB-device' already and voila: it worked. The next day I wanted to do this again: problems. So please allow me to describe my problems. problem #1: the inital screen comes up with the 3 choices. By doing nothing the choice 'grml' was started. Next was a scrren with the text: loading 2.6.18-grml, followed by approx. 180 dots (takes 10 minutes or so). What's this? At the end of this a message was displayed: BIOS data check succesfull (or something similar). Now we come to the booting-process. This works, a lot of lines are running on the screen. But we come to problem #2: a message appears: usb 2-2: reset high speed USB device using ehci_hcd and address 2 This will be repeated multiple times, some other messages are appearing and these messages appear over and over again. One of the messages between is: SCSI-error, return-code = 0x00050000 What's this? Can you please give me a hint. Thanks. AugustQ PS: on my desktop-machine I can easily switch operating system by removing the hard-disk (power off). I'm looking for a similar solution for my notebook. Opening a bay and swapping the disk is possible but I don't want it this way.

chroot again
by martin yazdzik 21 Mar '07

21 Mar '07

Dear M and friends, Just for information, and please realise I am not complaining: root@grmllap1 ~ # chroot /mnt/sda4 root@grmllap1 / # apt-get update Err http://www.debian-multimedia.org sid Release.gpg Could not resolve 'www.debian-multimedia.org' Err http://ftp.de.debian.org stable Release.gpg Could not resolve 'ftp.de.debian.org' Note that, when my experimental partition(/mnt/sda4) is plain old debian, I do the same thing and can do all package management or upgrades, install drives, and so on, from my working workhorse grml install, but, as now, when the /mnt/sda4 is a grml install, something stops me from using my internet connexion to fetch things. I think it may be a bind issue, or not? At any rate, this means I cannot work on one OS while in the other, which is silly. It obviously has nothing to do with the working grml, because every other one day install, zb, debian, SuSE, Sabayon, lets me use my running connexion to work. All other chrooted commands work, as long as, obviously, they are not x server dependent. Best, martin
