Description Gabriele 2004-11-21 15:26:08 UTC
Distribution: Debian GNU/Linux 3.1
Hardware Environment: ASUS P4C800, P4 2.4GHz, 512 MB Ram
Software Environment: 
Problem Description:
when I try to enable ACPI support (from power management) even if I don't enable
any other sub-options, the system crashes some seconds after kernel loading,
this is the last line I can read: ACPI: IRQ9 SCI: level Trigger (or something
like that I don't remember exactly). With ACPI disabled the boot is correct but
the CPU fan works at its maximum speed (which should be throttled in
concomitance with cpu temperature by Asus QFan feature)

Steps to reproduce: enable ACPI support inside the kernel
Comment 1 Len Brown 2004-11-21 18:24:47 UTC
did the ACPI-enabled kernel boot properly on this machine
in versions of Linux before 2.6.9?

Is it possible to capture the console output showing the failure using a 
serial line?  if no, how about a photo of the screen?

Do you get any additional warnings if you boot with
"acpi_dbg_level=0xF" "acpi_dbg_layer=0xFFFF3FFF"

I assume that the same kernel binary boots with "acpi=off".
Does it also boot with "acpi=noirq" or "pci=noacpi"?
Comment 2 Luming Yu 2004-11-22 00:53:20 UTC
I just googled, and found there is a bug report for ASUS P4C800 MB. 
From the description, It boots just fine with kernel 2.6.9-rc3 with ACPI 
enabled. And the problem there is about USB issue.

Comment 3 Gabriele 2004-11-22 11:11:23 UTC
ok, did some tryes and found that if I remove an usb peripheral the boot is
normal, no more crash, the peripheral is a flash memory card reader, made by
Apacer, if you need some more info just ask.
Btw, if I set acpi=off the kernel boot anyway, with acpi_dbg options, i don't
have any more output and with acpi=noirq or pci=noacpi i get this error:
ACPI: IRQ9 SCI: Edge set to level trigger
Comment 4 Greg Kroah-Hartman 2005-08-18 21:39:27 UTC
This should be resolved now, right?  If not, please reopen after testing with 
2.6.13-rc6 or greater.
