In the post where you show things going wrong, you have usb AND ethernet on 11. You say you have no usb devices.
How about this test then? = Disable USB in the BIOS and see what happens.
I tried that. It made no difference.
I'm still not clear on how to disable acpi in grub.conf. I tried
options ide-cd ignore=hdd acpi=off
and
kernel /vmlinuz-2.6.8-1.521 ro root=LABEL=/ hdd=ide-scsi acpi=off
and neither seemed to make a difference. In the latter case, I see this in /var/log/messages:
Sep 16 21:47:26 dell kernel: Kernel command line: ro root=LABEL=/ hdd=ide-scsi acpi=off
...
Sep 16 21:47:26 dell kernel: ACPI: Subsystem revision 20040326
Sep 16 21:47:26 dell kernel: ACPI: Interpreter disabled.
so I guess that worked. Then when it dies it says:
Sep 16 21:49:06 dell kernel: irq 11: nobody cared! (screaming interrupt?)
Sep 16 21:49:06 dell kernel: irq 11: Please try booting with acpi=off and report a bug

In the one case where it printed a stack trace I got:

I also get some other interesting error messages:
Sep 16 21:48:13 dell bonobo-activation-server (shannon-1810): iid OAFIID:BrokenNoType:20000808 has a NULL type
Sep 16 21:48:13 dell bonobo-activation-server (shannon-1810): invalid character '#' in iid 'OAFIID:This#!!%$iid%^$%_|~!OAFIID_ContainsBadChars'

Sep 16 21:48:15 dell modprobe: FATAL: Error running install command for sound_slot_0
Sep 16 21:48:15 dell modprobe: FATAL: Error running install command for sound_slot_1
What's the bonobo-activation-server message trying to tell me?
And, it looks like sound isn't working. And sound is using IRQ 11. Perhaps that's the problem? Way back in RH9, I think it was, I had problems making sound work as well. But FC1 fixed that. Maybe it's been broken again?
So, is this a well known problem or should I report it as a bug? If the latter, what additional information should I include in the bug report?
Thanks for any help.
