Description Andrey Taranov 2005-01-19 00:02:41 UTC
Using Minimal LiveCD 2004.3-r1. At the end of the reboot sequence, after the message about Unmounting file systems, I get this message:

/sbin/rc: line 123: 27037 Segmentation fault umount ${x} >& /dev/null

The machine does not reboot or halt afterwards. Just sits there with this message on screen. Another message of "no processes left in this runlevel" also appears...

This happens frequently, but not every time. Also got a USB-flash drive mount at the moment of reboot.

Reproducible: Sometimes
Steps to Reproduce:
1. Boot Minimal LiveCD 2004.3-r1, kernel gentoo without options
2. Insert flash drive
3. mkdir /mnt/flash ... mount -t vfat /dev/sda1 /mnt/flash
4. reboot (or halt)

Actual Results:  
/sbin/rc: line 123: 27037 Segmentation fault umount ${x} >& /dev/null

Machine still running, doesn't reboot.

Expected Results:  
A clean reboot or halt.

Will paste `emerge info` later today, if it's needed...

What if you umount the flash disk before you reboot?

If you can reproduce this with 2005.0, then please REOPEN.
