The following patch fixes this regression (confirmed by Andrey).
Please queue it for 2.6.23.  I'll come back later for another
try at sorting this all out.


PNP: remove SMCf010 quirk

If the quirk enables the SIR part of the SMCf010 device, the 8250 driver
may claim it as a legacy ttyS device, which makes the legacy probe in the
smsc-ircc2 driver fail.

BTW. Maciej Rutecki has said that "MCFG bug on hp nx6310" is not
a regression, so regression counter for ACPI == 0 (if I didn't
overlook something :))

Should be solved by 3b2b64fd311c92f2137eb7cee7025794cd854057, although 
differently from the the patch suggested above. So the regression should 
be gone a of -rc5.

A fix for this was merged by Linus prior to the release of 2.6.23-rc3.

Is there some special magic needed (like resubmit), or will you slurp this one
yourself?

This is already fixed in mainline

There is a real regression with failing builds on some old binutils on 
x86-64 know, but I don't know how to fix it.

Yes. Anyways it be likely a WONT-FIX -- aka document newer binutils
version required. We haven't had any other reports so likely
that version is not too widely used.

IOW: Either the Linux binutils >= 2.17.50.0.3 or the not yet released 
GNU binutils 2.18 are now required.

Debian 4.0 has older ones, and all distributions released more than a 
year ago for sure also have older ones (the required patch went into 
binutils CVS on 2006-05-30 and 2.17.50.0.3 was released on 2006-07-15).

Isn't that a bit too recent?
