My HD used to have 15 partitions, now I created another one, the 16th, but it is not recognized by udev.
Just a proof that no problem with adding the 16th partition:
$ sfdisk -V /dev/sda /dev/sda: OK
$ sfdisk -l | grep sda16 /dev/sda16 23509+ 24791 1283- 10305666 c W95 FAT32 (LBA)
Further, my Win2k accesses the sda16 without any problem.
$ dd if=/dev/sda16 of=/dev/null bs=512 count=1 dd: opening `/dev/sda16': No such device or address
Such a limit does not exist for udev:

Did you modify anything in the partition table of the disk? If so you must make sure that no partition of the disk is use, otherwise the BLKRRPART ioctl() fails of course and new devices won't be created therefore. (That's BTW the main reason why we chose to deactivate swap partitions by default for the new release of the live-cd.)
