It looks as if the root cause of the Dell PERC 2 issue is ACPI config- interrupts. I've been able to boot v2.6.25-rc8 with the kernel option "pci=noacpi".
I've got a bug open upstream: http://bugzilla.kernel.org/show_bug.cgi?id=10396 a git-rev-list shows 277 commits to ACPI between v2.6.20 and v2.6.22 so it's going to be a big job to narrow it down. -- -server kernel variant fails to boot on PowerEdge 2650 with AACRAID timeouts https://bugs.launchpad.net/bugs/149071 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
