Problem in hotplug?
Hallo l-k,
I've found some strange behavior of kernel:
# ps -afx

19 ? SW 0:00 [xfs_syncd]
33 ? S 0:00 /sbin/devfsd /dev
587 ? S 0:06 /sbin/syslog-ng
...etc...I'm using package hotplug from Debian sid distro:
ii hotplug 0.0.20031008-1 Linux Hotplug Scripts
I think, its abnormal operation: what if kernel will have not free PID?

I've found some strange behavior of kernel:
It's fixed in later -mm and -test7.
