I did
git bisect start drivers/scsi drivers/usb
git bad v2.6.18-rc1
git good v2.6.17
Heres what git bisect came up with
c32ba30f76eb18b3d4449072fe9c345a9574796b is first bad commit

[PATCH] USB: EHCI works again on NVidia controllers with >2GB RAM
From: Paul Serice <[email protected]>
The workaround in commit f7201c3dcd7799f2aa3d6ec427b194225360ecee
broke. The work around requires memory for DMA transfers for some
NVidia EHCI controllers to be below 2GB, but recent changes have
caused some DMA memory to be allocated before the DMA mask is set.

What would be the way to revert that patch from 2.6.18-rc4 to confirm it's the culprit?
Heres the output from git bisect log
