------- Comment #120 from [EMAIL PROTECTED]  2007-12-21 04:19 -------
Well, i'm completely at a loss to explain this, but the problem seems to have
gone away of its own accord on my system! It's an R61 (8932-A13), running
Fedora 8, with a home-built 2.6.23.9 x86_64 kernel which previously had the
problem - and, as far as i know, i haven't done anything to fix it.

I can't say for certain when it disappeared, as i don't normally shut down and
reboot my system for days on end (i use hibernate or suspend at night).
However, i think it disappeared yesterday.

The only thing i can think that could have fixed it is an automatic update of
the WinXP system that's dual bootable. I almost never boot into Windows, but i
did yesterday - and Windows did an automatic update. Perhaps it did some BIOS
configuration that's persistent.

Naturally, i can't undo this and verify my suspicion. And i can't yet say for
certain that the problem's really gone away and it's not just taking much
longer than usual to Linux to kill that interrupt, for some reason. But it's
currently been up for 30 mins without that interrupt being disabled.

I first noticed this morning that those two USB ports were still working, even
though the uptime was about 12 hours. I had a (Fedora) kernel update yesterday
and i wondered if that had fixed it, so i rebooted with a kernel that i knew
still had the problem and it appears to have gone away.
