David, can you try to fix this up.  It all started with your uhci
patch...

I have tried, two or three times now ...

The problem is that nobody has ever reported back with results from
testing any updated patch (see attachment, the guts of this being
from Alan Stern).  Sort of makes trying be a moot point ... :)

It's OK with me if you just revert the patch that adds a uhci_reset()
entry, but based on what I saw with EHCI and OHCI that'll just turn
up a different set of problems with certain BIOS configurations (none
of which I have) ... which will need to be fixed by having a UHCI
reset sequence that works correctly from _all_ initial states.

So I'm the first one? ;)

Your patch (http://www.ussg.iu.edu/hypermail/linux/kernel/0309.3/0341.html) 
FIXES things for me :-)

This time I've tried 2.6.0test6 + all acpi patches from 2.6.0-mm1 (ls *acpi* 
in akpm broken-out directory) + your patch and things work fine :)
Note that 2.6.0+all acpi patches from 2.6.0-mm1 without your patch doesn't 
work.

Since then I got mixed reports -- not sure I trust them.

OK, that's good to hear.  There are two patches that seem
to work to various degrees.  This isn't the least conservative
fix (that'd be http://lkml.org/lkml/2003/9/29/74, returning
to that odd "reset before kicking bios off" sequence) but it's
good to know this also behaves.

Re: USB problem. 'irq 9: nobody cared!'

[Yaroslav Halchenko]

I've tried again with recent bk12 kernel and this patch worked... 

May be I was too tired and actually didn't patch the first time I
tried, and then reported to you that it didn't help - I'm sorry. Will
check later if it is the case.

Thanx for your help

Sincerely 
Yarik
