Public bug reported:
Suspend-to-mem fails to resume when suspend while on battery then
resumed with AC plugged in on a Lenovo T61 (Intel video) w/ Ubuntu 7.10
x86_64 2.6.22.14.52
How to reproduce:
1) First, run the laptop on battery power and login
2) do something
3) suspend to memory
4) now, plug in the ac adapter while the computer is still suspended
5) now, wake up the computer right after plugging in --- it freezes, needs a
hard reboot
Another situation:
1) run the computer while plugged in, but the battery is low
2) do something
3) suspend to memory
4) wait a while until the battery is charged
5) wake the computer up... it freezes, needs a hard reboot.
Suspend-to-mem resumes ok if on AC at suspend and resume. Suspend-to-
disk doesn't have the same symptoms and works ok.
