[OpenAFS] Weird conflict between openafs kernel module and nvidia driver on Ubuntu

[Karl M. Davis]

As part of my standard setup, I've been editing /etc/openafs/afs.=
conf:
<<
...
#OPTIONS=3DAUTOMATIC
OPTIONS=3D"-chunksize 20 -memcache -blocks 65536"
>>

Is that not legit?  Can't recall where I was told to do that, but=
 I'm guessing it was likely someone in the IRC channel.

Thanks,
Karl

just looking through your dmesg output, i think this is likely yo=
ur

out of vmalloc is 'bad'.  looks like your are using the memory ca=
che and
it is probably chewing up a bit of memory.  what chunksize are yo=
u using?
