This coincides with this, not sure if it is related: Raw Audit Messages type=AVC msg=audit(1319482070.930:685): avc: denied { write } for pid=21425 comm="paster" name="etc" dev=dm-2 ino=1019341 scontext=system_u:system_r:piranha_web_t:s0 tcontext=system_u:object_r:piranha_web_conf_t:s0 tclass=dir type=SYSCALL msg=audit(1319482070.930:685): arch=x86_64 syscall=open success=no exit=EACCES a0=22cb0b0 a1=241 a2=1b6 a3=9 items=0 ppid=21404 pid=21425 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=paster exe=/usr/bin/python subj=system_u:system_r:piranha_web_t:s0 key=(null) Hash: paster,piranha_web_t,piranha_web_conf_t,dir,write
unless you can reproduce this without the proprietary module, there's not much we can do with this.
What proprietary module? The only thing that I think I have would be kmod-wl for the Broadcom wifi NIC. $ rpm -qa | grep kmod kmod-wl-5.60.48.36-2.fc15.9.x86_64 kmod-wl-2.6.40.6-0.fc15.x86_64-5.60.48.36-2.fc15.9.x86_64
I'm confused as kmod-wl doesn't seem to be related to this kernel dump. hfsplus seem to be the root of this problem, not kmod-wl
:[679635.081949] page flags: 0x40000000000004(referenced) Something has set that high bit, which is why the kernel is freaking out. It looks like memory corruption of some kind. That hfsplus blew up may just be a side-effect, that that was the module that owned the memory those page-tables pointed to. Which is why we want to rule out the modules we don't ship.
