There is a problem in actual kernel with openafs-kernel-1.4.10. The corresponding bug in openafs is http://rt.central.org/rt/index.html?q=124737. The issue should be fixed in 1.4.11 (info from sxw in #openafs). Could you please bump? Can I assist you on it? I had to remove the openafs-dprintf.patch to compile net-fs/openafs - job left to do was only a simple version bump. g, mueli p.S.: here is the kernel trace for reference Aug 21 11:26:20 michael [ 3289.504797] ------------[ cut here ]------------ Aug 21 11:26:20 michael [ 3289.504802] kernel BUG at kernel/cred.c:360!

Version bumped to 1.4.11. Any test results are welcome.
Looks good indeed! I've already used my "selfmade" ebuild, therefore I can confirm that the issue is fixed in 1.4.11. As far as I'd say this would be a release to got stable? What do you think? g, mueli

Bug 273723, comment 5, indicates the pam_afs.so.1 that openafs-1.4.11 produces is broken. Because of this, stabling 1.4.11 does not seem like a good option.
