2.6.19-rc1: known regressions

2.6.19-rc1: known regressions

[Adrian Bunk]

Contrary to popular belief, there are people who test -rc kernels
and report bugs.

And there are even people who test -git kernels.

This email lists some known regressions in 2.6.19-rc1 compared to 2.6.18.

If you find your name in the Cc header, you are either submitter of one
of the bugs, maintainer of an affectected subsystem or driver, a patch
of you was declared guilty for a breakage or I'm considering you in any
other way possibly involved with one or more of these issues.

Due to the huge amount of recipients, please trim the Cc when answering.

Slightly off topic, but let me report a "metoo" as far as testing -git
goes (you can even find a suspend2-against-current-git tree on
kernel.org now!), and some positive progress: for the first time in
months, I'm reliably suspending and resuming my amd64 based laptop. I
don't have an exact cause, but would guess at Andi's multitude of
patches and/or any cpufreq fixes that might have slid in there too. It's
been really strange writing software that others can use reliably, and
not being able to reliably use it yourself! Kudos to all the authors of
suspend/resume bug fixes that have gone in!

[patch] x86, fix rwsem build bug on CONFIG_M386=y

find the fix below.

Subject: [patch] x86, fix rwsem build bug on CONFIG_M386=y
From: Ingo Molnar <mingo@elte.hu>

CONFIG_M386 turns on spinlock-based generic rwsems - which surprises the 
semaphore.S rwsem stubs. Tested both with and without CONFIG_M386.

Should be fixed once Linus pulls the powerpc.git tree.
