Description Michal Jaegermann 2005-12-23 02:07:11 UTC
Description of problem:

An attempt to boot 2.6.14-1.1777_FC5 generates oops and kernel wedges trying
to identify disk devices.  Opps is pretty extensive and nothing really works
yet beyond a screen output so it is hard to record traces.  Here is what
I retyped from a screen lines which seem to be the most relevant.

ACPI: PCI Interrupt 0000:00:0f.0[B] -> GSI 20 (level, low) -> IRQ 0
PCI: Via IRQ fixup for 0000:00:0f.0, from 5 to 0

(at this point a machine is dead but a reset button still works).

Note an interrupt routing to IRQ 0.  In the last working kernel, which
on this machine happens to be 2.6.14-1.1773_FC5, the corresponding line
looks like this:

ACPI: PCI Interrupt 0000:00:0f.0[B] -> GSI 20 (level, low) -> IRQ 169

and there are no problems in accessing drives.  As a matter of fact this
bug seems to be related to bug #176284 only results are considerably more
dramatic.  This impression is also supported by this detail that adding
'acpi=off' to a boot command allows to boot (and networking then happens
to work too).

dmesg output for a working kernel and for 1777 with acpi off is attached.

Version-Release number of selected component (if applicable):
kernel 2.6.14-1.1777_FC5

How reproducible:

Comment 1 Michal Jaegermann 2005-12-23 02:08:47 UTC
Created attachment 122549 [details]
dmesg output from the same machine and a bootable kernel

Comment 2 Michal Jaegermann 2005-12-23 02:10:45 UTC
Created attachment 122550 [details]
dmesg output for 2.6.14-1.1777_FC5 with 'acpi=off'

Comment 3 Dave Jones 2005-12-23 18:36:50 UTC
should be fixed now (backed out acpi changes, and reported upstream).

Comment 4 Michal Jaegermann 2005-12-23 20:48:47 UTC
> should be fixed now
Indeed.  I am booting 2.6.14-1.1783_FC5 again without using 'acpi=off'.
Also networking problems as described in bug #176284 disappeared. Not a very
big surprise.  Thanks.
