Hi,
I must say I'm really impressed with the progress that swsusp made since I
tried it last time (close to 2.6.10-rc1 as I recall). Now I've been using it
for a couple of days on 2.6.10-rc3-mm1 and It's never refused to suspend the
machine because of the lack of (contiguous) memory which happened very often
before, and it seems to be much faster. Using it my notebook has reached
more that 1 day of uptime recently, wich was practically impossible
previously. It's a great job and vast improvement for which I thank you very
much!
Still, unfortunately, today it crashed on suspend and I wasn't able to get any
useful information related to the crash, because swsusp apparently does not
send some of its messages to the serial console. In particular, anything
from within the critical section is not printed there and that's why I think
(I'm not sure though) that the crash occured in the critical section. Could
you tell me please if it's possible to make all of the swsusp messages appear
on the serial console and, if so, how to do this (I've already tried "dmesg
-n 8" and "echo 9 > /proc/sysrq-trigger" but none of them helps)?
Greets,
RJW

Hmmm, unfortunately I did not changes in that area. Perhaps memory
managment was fixed/improved?

Using regular vga console and digital camera seems to be popular way
to get dumps. I'm not sure why swsusp critical section interferes with
serial, perhaps serial console support has to "know" about serial
console and not suspend it during suspend() call?

Well, the problem is that:
1) I don't have a DC,
2) even if I had one, my VTs go nuts after switching to X and then they only
display garbage ... :-)

It didn't do that before 2.6.9 or so. Something must have changed afterwards.
And the serial console shows messages that appear right before writing the
image to swap (like "swsusp: Version: ..." etc.).

You may want to remove suspend() support from serial drivers and see
what happens... Or find exact patch that broke it.

Have you tried an -rc3-bk13 snapshot? Some changes went in related to
ALSA drivers and swsusp/ACPI suspend, perhaps it will fix the problem.

Unfortunately, I have no time for playing with -bk kernels. I'll wait for
-rc4 or 2.6.10 or maybe Andrew will include this fixes into -mm before?
