git bisect incomplete.
2.6.37-rc1 works fine.
i tried to bisect this but i got to a point where the system would hang before suspend. skipping patches got me nowhere.
Bisecting: 39 revisions left to test after this (roughly 5 steps)
im attaching the bisect log just it case it proves useful.
the system is an everex stepnote sa2053t.
it had several issues concerning suspend/resume in the past. but this one is a bit different.
when this system tries to come back to life. it shows an empty terminal with a stuck cursor. sysrq-REISUB reboots the system.
1. Does the problem also happen in the minimum config, ie. when booted with
2. The only commit I can think may cause this problem to happen from the
first sight is 48fcfc8 (i915: reprogram power monitoring registers on resume).
Can you try to revert it and see if that helps, please?

i did revert this on rc3 but it didnt help.
apparently this got fixed in rc4.
will do more testing in the week, but i guess you can close this for now.
