Subject: [REGRESSION] nfsd crashing with 3.6.0-rc7 on PowerPC
Howdy,
While running 3.6.0-rcX I am having a few issues with nfsd on my PPC970 based system. For some reason every time I actually end up accessing an NFS share on it, it crashes away at random points. It looks a lot like corrupted pointers in all logs. I also can't reproduce the oopses without nfsd in the game. Doing the same workload that crashes over NFS locally on the box (git clone -ls) works just fine.
The mount was done simply without parameters:
lychee:/home/agraf/release on /abuild/agraf/autotest_e500/lychee type nfs (rw,addr=10.10.1.189)
My exports on the host is also quite simple:
/home/agraf/release *(async,rw)
Below are OOPS excerpts from different rc's I tried. All of them crashed - all the way up to current Linus' master branch. I haven't cross-checked, but I don't remember any such behavior from pre-3.6 releases.
Alex
