vmalloc, xfs_buf_get: failed to map pages

[Mario Bachmann]

Hello, 

on a 32bit machine, I have big problems with Linux 2.6.34. 
With Linux 2.6.33.4 everything runs fine. 

I do not know where to search for known bugs in xfs.

/var/log/messages shows a lot of lines:

Jun 19 11:43:15 amd2000 kernel: vmap allocation for size 4194304 failed: use vmalloc=<size> to increase size.
Jun 19 11:43:15 amd2000 kernel: xfs_buf_get: failed to map pages

What to to?

Mario
