Public bug reported:
Binary package hint: linux-image-2.6.22-14-xen
The linux-image-xen kernel boots fine as long as the virtualization
support (VMX) is turned off in the BIOS, but when I turn it on in the
BIOS, boot on dom0 hangs. The last console output is:
Setting up standard PCI resources
I note that on a successful boot with VMX disabled in the BIOS, the line
above comes right before the following ACPI stuff:
ACPI: EC: Look up EC in DSDT
ACPI: Interpreter enabled
ACPI: (supports S0 S3 S4 S5)
ACPI: Using IOAPIC for interrupt routing
Xen dom0 would boot when "acpi=off" was passed to Xen on boot. I tried
all the acpi Xen boot options I could find with the following effects:
acpi=off -> Boots, no ACPI
acpi=ht -> Boots, no ACPI
acpi=force -> Hangs
acpi=noirq -> Hangs
acpi -> Hangs
acpi=strict -> Hangs
acpi=1 -> Hangs
There is no combination that boots dom0 with VMX enabled and ACPI
working.
My system is a Core 2 Duo T7200 Toshiba Satellite U205-5067 laptop
running gutsy x86.
