Bug Description
On ppc with 2.6.38-11-powerpc #47, udev spawns c. 40 instances, applications such as
29404 root 20 0 16036 3936 3264 S 14.0 0.4 0:22.72 udisks-daemon
29392 jrh 20 0 12684 4912 3408 S 13.7 0.5 0:22.68 gvfs-gdu-volume
29920 jrh 20 0 29156 9660 6764 S 10.1 0.9 0:15.60 gdu-notificatio
473 messageb 20 0 4904 2220 940 R 9.8 0.2 0:17.12 dbus-daemon
295 root 18 -2 3536 1136 428 S 7.5 0.1 0:46.40 udevd
then conspire to hog almost all CPU, rendering the machine useless.
This did not happen with previous kernels. It also does not happen on ia32 and x86_64 with the same kernel version.

Same here on iBook G4. UdevLog.txt says that kernel reports media change over and over again. If you insert an audio CD, udev still wastes CPU cycles on blk_id et al but at least udisks-daemon doesn't run all the time.
