Bug Description
SRU Justification: This can cause an oops at 000068. This will happen to all processes confined or unconfined when name resolution fails at exec. This can happen in a couple different cases, applications like psx, and mugen munge the process during their decrompress and set up links so that a valid name does not exist. The other way that this can happen is executing code from a path that has been lazily unmounted. This can occur with nfs and automounters, or any mount point that gets unmounted with lazy unmount allowed.
I use kerel 2.6.31-11
whene i start the Playstation Emulator epsxe came a message killed and that crashreport.
The Playstation Emulator pSX doesen t work too. but it is not the same problem.
Whit the Kernel 2.6.29 the Emulators run very good. but since one week i have problems with the sound ander kernel 2.6.29.
When i start linux with kernel 2.6.31-11 came a black screen. then i go in a console by pressing strg alt F2 and make startx.

Hello, bprm_set_ creds) , but no : even with apparmor removed, the same crash happens.
I am affected by (apparently) the same problem, with the same app (epsxe v1.6.0).
This app worked fine with Kubuntu Jaunty, it no longer starts with Kubuntu Karmic RC.
I attached a bit of my "dmesg" output.
Anyway, this issue looks a lot like bug #446164 too. I removed the apparmor package to see if it changed anything (since the kernel message mentions apparmor_
Thanks.
