Version: 0.042-1
Severity: normal
Hi,
I have added a new partition on my hdd from the free space.
The new device (/dev/hdb1) was not in the /dev directory.
I tried to add it restarting udev:
/etc/init.d/udev force-reload (or restart)
It said that it was creating initial nodes then segfault in line 129 of
/etc/init.d/udev
i can see the creation of the nodes in the systlog, then the following:
....
Nov 13 18:14:00 tangerine udev[5508]: creating device node '/dev/ttyab'
Nov 13 18:14:00 tangerine udev[5508]: error: timeout reached, event probably not
handled correctly
Regards
Jean-Luc

I recompiled udev unstripped and got a core.
I used gdb to get a backtrace but I failed. gdb says "no debug symbols found".

So, nothing interesting.
With the dbg libc, I've a lot of mesages in the syslog:

Maybe 30 seconds timeout are too short for the dev.d/ scripts or a slow
syslog. Later udev versions have 120 seconds and do not log in the
udevstart case.

This is probably cause by using syslog() in a signal handler. It's fixed
in a later version.
