Just out of curiosity, does this happen if you boot with "acpi=off" on the boot
Created attachment 6294 [details]
early ehci irq disable
This patch tweaks some BIOS-related behavior that can appear during
initialization or with kexec(); it's in the 2.6.15 queue. It might
explain the problem you're seeing.
You might also try booting with "usb-handoff" set on the kernel
1. booting 14-rc4 with acpi=off doesn't help.
2. patching the kernel so that the ehci controller is halted before reboot
doesn't help alone but...
3. the patched kernel with the "usb-handoff" boot option booted just fine.
Tell me if you need more info.
Looks like your BIOS just demands the usb-handoff to be done
early; there are some systems that need that. In fact, enough
that we'll probably make that the default at some point.
Since you now know about that flag, I'll close this bug.
is this patch going to enter 2.6.14 or it remains in the 2.6.15 queue?
Bug 5433 was marked as a duplicate of this bug, but I know for certain that my
machine has worked without problems in the past and as such should not require
any special kernel options. Please consider reopening the bug or making
usb-handoff the default asap. I will be testing if it fixes my problem.
I applied the patch and added usb-handoff in the grub menu but it did not solve
To Petteri R
To Borislav Petkov ... the patch shouldn't be needed
if you're using usb-handoff and the only issue you're
seeing is at boot time. So it should be no problem
for you that it won't be merged quite yet.
... however, I booted this morning with usb-handoff and it crashed at the same
point again... maybe useb-handoff with the patch doesn't work OK. Should I
remove the patch and use _only_ usb-handoff as a boot option?
2.6.14-rc5 doesn't boot with 'usb-handoff' and the machine halts at the same
point in the boot process.
correction: the usb-handoff boot option helps only when you reboot. Otherwise,
on initial boot, the machine hangs. For 2.6.14-rc5-mm1 this is also the case.
Closing this again. (a) 2.6.13 worked, contrary to comment #2,
but most importantly (b) after a BIOS update, 2.6.14 works too.
