Additional info:
Hmm, didn't manage to reproduce same crash. From the output I asume it's more kernel bug. May I have some comments from kernel people please?
which kernel version is this ?
2.6.11-1.1369_FC4 Also, it is in the kernel, when I disabled the multipath caching it no longer crashed... experimental feature probably not needed in fedora core base kernel...
Sorry exact feature to disable is: IP_ROUTE_MULTIPATH_CACHED
This is fixed in the errata kernel.
