Strange, problem went away after reboot. I guess I'll write it off as
an acpi glitch... there's definitely something strange going on with
backlight around s2ram: during normal operation, backlight changes are
fast. After s2ram, backlight change from keyboard takes 300msec or so.

Is this a regression compared to 2.6.18 or an older issue?
If it's a regression can you bisect?

This was on a pre -rc1 git tree.
I've been using -rc1 since it's out and does not happen to me anymore.
So we probably can write this off as a memory corruption
issue that got fixed in between.

Slowness is not something I'd classify as serious problem, and
breakage is not reproducible. Ignore it for now.

Thanks for the information, I've removed it from the list.

Yes, I'm seeing that too. It's not just keyboard brightness changes;
gnome does some fadeup effect, which takes ~300ms/step as well.

Unfortunately, this came back after using 2.6.19-rc1 for a couple of days
without reboot. And I just re-tested and was able to re-produce the problem on
2.6.19-rc2, as well. So the problem is still there, with the same symptoms:
after usig machine for a while, or under stress (e.g. if I do a full kernel
compile), I stop getting any ACPI events.
tail -f /var/log/acpid
does not show anything, even on Fn/F4 which is supposed ot be always enabled.
Restarting the acpid doesn't do anything either - ACPI starts working
again, for a while, only after reboot.
Worked fine under 2.6.18 (I was running vanilla + this patch
http://lkml.org/lkml/2006/7/20/56 which made it into upstream since then).
Any ideas? How to debug this?
