** Tags removed: needs-upstream-testing ** Tags added: kernel-bug-exists-upstream performing-bisect ** Description changed: 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. + WORKAROUND: BIOS -> disable 1394 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-8-server 2.6.38-8.42 ProcVersionSignature: Ubuntu 2.6.35-28.50-server 2.6.35.11 Uname: Linux 2.6.35-28-server x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
