Openafs 1.4.11 with the newly stablized gentoo-sources kernel 2.6.32-r7 gives kernel panics similar to those mentioned in bug #282196, although this problem is not supposed to exist with 1.4.11, as I understand it. In case this is some other sort of panic, I will paste in the messages I get in my particular situation. I experienced no problems with 1.4.11 and the previous stable 2.6.31-r10. Reproducible: Always Steps to Reproduce: 1. Build 2.6.32-r7 2. Rebuild openafs-kernel 1.4.11 with new kernel 3.

Indeed. Resolving CANTFIX
(In reply to comment #2) > Indeed. Resolving CANTFIX > You of course should handle this as you see fit, but I think it's more appropriate to make this as a duplicate of bug http://bugs.gentoo.org/show_bug.cgi?id=310627, since indeed Gentoo make a kernel stable without a stable openafs even being in the tree. Alternately, you could make bug #310627 ICANTFIX and to indicate you have given up on supporting OpenAFS in Gentoo at all.
It might be worth considering adding a kernel version check to openafs-kernel-1.4.11, so that unsuspecting users won't run into this problem.
*** Bug 316197 has been marked as a duplicate of this bug. ***
openafs-kernel-1.4.12.1 should fix things
