Subject : 2.6.24 regression: hibernation hangs on "Suspending console" in low-battery condition

Suspend-to-RAM in normal battery conditions (or without battery)
works. With 5% threshold there's a visible indication of alarm from *firmware* (battery LED flashing) and the subsequent "emergency" suspend fails.
Could you please try to comment out battery_update at battery_notify()?

Always return valid status
There is also this patch, might help.
I already used this patch in rc2 - it made no difference (as I mentioned in original mail thread). In rc3 I am unable to trigger this problem with or without this patch. I tried to set BAT1/alarm to some higher value but either I do not understand what it does or it was actually red herring.
Well if it won't be back in rc4 I'd say it has to be removed from list of regressions.
I had to test and you understand, it takes several hours for battery to discharge so I can do it once a day at the most and I have to do it several times to be sure ... it takes time, you know ...
I'm closing this regression as suggested by Andrey - please re-open it if you see this problem agan.
