[OpenAFS] Openafs kernel problems

[Dave Botsch]

I'm seeing a fair amount of these on a daily basis. At this point, I
believe I'm seeing them mostly from my RHEL6/64 machines running the
latest RHEL6.5 kernel and oafs 1.6.5.2 :

(Thoughts?)

abrt_version:   2.0.8
cmdline:        ro root=UUID=2001c35a-147a-4854-bf48-37681bff20b6 rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb rd_NO_LVM crashkernel=129M@0M rhgb quiet rd_NO_DM
kernel:         2.6.32-431.3.1.el6.x86_64
last_occurrence: 1391195007
not-reportable: A kernel problem occurred, but your kernel has been tainted (flags:P           ). Kernel maintainers are unable to diagnose tainted reports.
