Public bug reported:
Repeatable kernel panics after upgrade to 11.04 on kernel 2.6.38-08.
Tried pre-release kernel 38.10, same.
Reverted to 2.6.35-28 no problems.
I usually boot my system with clock=acpi_pm. This resolved some vmware
stability some time back. Have tried with and without various acpi
options to no avail. Have also enabled and disabled acpi in bios.
System is a dual xeon server, 8GB, ASUS Z7S.
Absolutely rock solid months on end.
Panic does not alway happen at same time. But it always happens within a
few minutes (at best) of booting.
Thinking acpi and possible thermal issues, have forced all fans to max
in bios (setting threshold temps down). No resolution.
Bug report package generated while running 2.6.35-28 kernel. System
otherwise unchanged.
Will attach photo of panic screen.
