Summary: IRQ roututing for PCI express bus broken
Product: ACPI
Version: 2.5
KernelVersion: 2.6.22-rc7
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: Config-Interrupts
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Most recent kernel where this bug did not occur: 2.6.22-rc7
Distribution: Ubuntu gutsy (developnent release)
Hardware Environment: AMD Turion X2, NForce C51
Software Environment: 2.6.22-rc7 x86_64 AND x86
Problem Description:
System hangs on boot when "setting up timer" or "loading additional drivers" if
not nolpic or pci=noacpi is added.
If nolpci or pci=noacpi is added the system can boot, but the IRQs for the
second PCI express buss are note assigned.
