Software:
1. Suse Linux SLES 9 SP1
2. kernel linux-2.6.12-rc4-mm1
3. Kexec-tools-1.101 + kdump patch
4. FSRacer - a simple test script doing loads of filesystem operations 
   like creat/open/read/write/link lots of files
5. spinlock testmodule to force spinlock deadlock with irq disabled.

Test-procedure:
- Ran test suite FSracer over LVM partition and the test ran without
  failures. Forced system hang by inserting spinlock test module and
  then invoked kernel panic with sysrq-c. Secondary kernel booted properly
  without any issues. I was able to take the dump using sysrq keys.
