I've been busy and have been a bit late responding to this. In short,
have a problem with disk performance on a HP Pavilion laptop in the
2.6.1[34] kernels (it works fine under 2.6.12.x). I've summarized much
of the tests I've run on in a post to linux-kernel and linux-ide (when
we thought it was a problem in the ATIIXP module) at:

http://marc.theaimsgroup.com/?l=linux-kernel&m=112802950411697&w=2

After working with Stefan for a bit, we determined that the problem is
in the ACPI modules (in fact setting ACPI=ht at boot fixes it, although
other things seem to break, as described below). Stefan suggested I
repost the bug to the linux-kernel list, and so here it is.

Is this read performance, write performance, or both? And have you checked the output in dmesg? See anything with blockdev? Detailed lspci output and /proc/interrupts?

I don't have anything in mand, just looking for information which might in some universe get diddled by ACPI.
