Description Christian Nygaard 2007-08-27 20:09:54 EDT
Description of problem:
If you create multiple snapshots with LVM and then use lvremove
the kernel panics. This also happens if you lvcreate, do not use lvremove
and just reboot, then the system always panics.

Version-Release number of selected component (if applicable):

How reproducible:
Create multiple lvm snapshots and then remove them, when you remove
the last snapshot the kernel panics.

Steps to Reproduce:
1. i=0 ; while [ $i -lt 18 ] ; do lvcreate -L32M -s -n test$i /dev/system/var ;
let i=i+1 ; done

2. i=0 ; while [ $i -lt 18 ] ; do lvremove -f /dev/system/test$i ; let i=i+1 ; done

Actual results:
Kernel Panic

There is no syslog attached output but I am almost sure that this is duplicate
of bug 211525.
If it is different problem, please reopen the bug and attach syslog with OOps
information, thanks.
