Comment 53 for bug 784484

Also experiencing similar here. Asus Z7S dual Quad Xeons. Server kernel 35-28 no problem at all. upgrade to 38-8 with Ubuntu 11.04 and am in disaster zone.

From some time back I had to add clock=acpi_pm to stabalise a previous stability problem. Have tried every variation of this with 11.04 to no avail.

Have removed all sensor drivers and chipset modules.

Have enabled pre-release repos and installed kernel 38-10 still getting panics.

Now back on 35-28, stable.

Any help appreciated. Happy to assist any testing.

Have been browsing lots of forums and there seems to be a common thread on these panics around ACPI and particualrly ASUS - perhaps some of their erlier implementations had some broken stuff thats not being identified until this newer kernel?

Rehardless, this is definitiely a change in this kernel causing grief. And its not fixed in 38-10.
