Subject: 2.6.26-rc1 sound regression

Hi,

my sound stops working with 2.6.26-rc1,
alsaplayer makes intermitted random noise.
Bisecting worked fine and the last steps were:

$ git bisect good
Bisecting: 9 revisions left to test after this
[71848d687e2a477cb7c68a854d8fdeaa5dff0ffc] x86: remove virt_to_bus in pci-dma_64.c

$ git bisect good
Bisecting: 4 revisions left to test after this
[8f19ca1341a6d89bd96e2e69e6e10f46d3258089] x86: unify gfp masks

$ git bisect bad
Bisecting: 2 revisions left to test after this
[45a07e774950ef479f8996c0e2c5550dd6440453] x86: use a fallback dev for i386

$ git bisect good
Bisecting: 1 revisions left to test after this
[5fa78ca75d8e67063948a01b51594a0904af5710] x86: retry allocation if failed

The last kernel is bad.
Checked 2.6.26-rc2 too which is bad.

This is a 10+x year old laptop, but it does useful work for me.
The driver is snd_sb8.
