Description Nicolas Mailhot 2002-11-16 04:12:36 UTC 
[ This is just a rehash of the usb part of bug #10 so people not interested in
the networking part can follow this bug. While bug #10 form may have been good
for linux-kernel, compound bugs are really not a good bugzilla practice ]

Exact Kernel version: 2.5.46-bk2 + about a dozen 2.5/2.5-ac kernels I've tried
in the 2.5.44-2.5.47 range

Distribution: Red Hat Rawhide

Hardware Environment:
- Gigabyte GA -7VAX http://www.giga-byte.com/products/7vax.htm (Via KT 400)
- a bunch of usb1 devices plugged on an external usb2 nec hub

Problem Description: building a kernel with local apic (with and without
io-apic) kills usb at startup. The rest of the hardware initialization is fine.

Seems a *lot* of people are bitten by this bug.

See bug #10 for more info.

This is a ACPI problem with the interrupt routing, not a USB problem.

So it really is the same as bug 10

Severity -> low since bug #10 is fixed and this was a workarounf scenario
