xen HV does not boot - ACPI
Last modified: 2014-03-16 22:58:15 EDT
Description of problem:
My machine, it does not boot
Xen hangs before it can mount root
Looking at it I do spy
Where it hangs - ACPI
Normal kernels boot just swell
acpi=off does as well
Version-Release number of selected component (if applicable):
Created attachment 124784 [details]
xen boot log
Created attachment 124785 [details]
normal boot log
Created attachment 124836 [details]
normal boot log. right one this time.
If I build with CONFIG_ACPI_DEBUG, it hangs at:
ACPI: Subsystem revision 20060127
evgpeblk-0941  ev_create_gpe_block : GPE 00 to 1F [ _GPE] 4 regs on int 0x9
So, some testing of various combinations:
A = stock one in 1.1955
B = self-built from 1.1955 sources. gcc-4.x
C = self-built from 1.1955 sources. gcc32
A = FAIL
B = PASS
C = PASS
(note that 'PASS' in this case boots userland with a an interrupt
screaming at a rate of ~3 million interrupts per minute.)
Still hangs on 2009.4.2, still easily worked around with acpi=off.
Hmm -- what hv/kernel options are you using here? Are you using "sync_console"
when capturing serial console?
Machine died. *shrug*. Probably can be closed unless it pops up somewhere else.
