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.

Could you please open a bug report for this, against acpi at bugzilla.kernel.org? Thanks. ^ permalink raw reply [flat|nested] 4+ messages in thread

As per Andrew Morton's suggestion, I've opened a bug at bugzilla.kernel.org (http://bugzilla.kernel.org/show_bug.cgi?id=5594), it has all the relevant information (basically copies of what I've posted on linux-kernel and linux-ide). So far it's still sitting there as "NEW". David On Mon, 2005-11-14 at 16:17 -0500, Bill Davidsen wrote: > David Ronis wrote: > > I've been busy and have been a bit late responding to this.
