I tried:
kernel /vmlinuz-2.6.8-1.521 ro root=LABEL=/ hdd=ide-scsi acpi=off pci=noacpi noapic
I don't know what ACPI and APIC are, or what the difference is between them,
and I wasn't sure which people were recommending, so I tried both.
It made no difference.
It might also be worth temporarily disabling both sound and networking:
try commenting out the appropriate lines in /etc/modprobe.conf or
setting alias sound off.
I disabled sound in the BIOS. Made no difference.
I disabled ethernet in the BIOS. The system hung coming up when it
tried to start sendmail.
Just a reminder, I can reproduce this easily as follows...
I try to login through the GUI login screen to a test account that has
no special dot files. The login hangs after putting up the "metacity"
icon. I login from another machine using ssh and kill gnome-session.
That kills the hung login but also immediately displays the "Disabling
IRQ #11" message in my ssh window. The GUI login screen continues to
function and I can use it to reboot the system.
Disabling acpi and turning off all sorts of things related to IRQ #11
doesn't seem to make any difference.
Is it time to report a bug?
It might *also* be worth playing with kernel.org kernels.
I'll wait for Fedora Core 3 before wasting time doing that.
