[Bug 55967] Crash while booting kernel when Legacy USB is enabled in BIOS

[Greg Hackmann]

Public bug reported:

I'm trying to install Ubuntu 6.06 AMD64 on my new PC, and I'm unable to
boot the install CD when Legacy USB is enabled in my BIOS.
(Unfortunately, I'd rather not disable this option, since my USB
keyboard doesn't work with GRUB when it's off.)  SuSE 10.1 x86-64
installs and boots fine with this option enabled; so I think that either
an Ubuntu kernel patch is causing the problem, or the SuSE kernel has a
patch that works around it.

With the standard boot options, my PC stops responding after the
"Booting the kernel" message.  If I remove the quiet parameter, then the
last kernel message that is printed is

"[   36.808292] PNP: No PS/2 controller found. Probing ports directly."

Adding acpi=off, noacpi, noapic, and/or nolapic to the boot options
doesn't seem to make a difference.

This problem occurs with the Ubuntu 6.06 AMD64 CD, and also with the
Ubuntu Edgy Eft Knot 1 AMD64 CD.  I'm using an Abit AB9 Pro motherboard
with BIOS version 1.1.
