OK, I tried. And I want you to be fully aware of the extreme personal
cost at which I did that. Because every time I have to interact with
Windows 95, I damn near have a stroke. This exercise probably took 2
years off my life span.
Anyway, in Windows 95 I found a couple of places where you could
enable/disable waking up the machine on an incoming call. Both were
already disabled.
Back in Unix again (whew!), I made it fail again. I did that by
"apmconf -e" followed by "zzz". It resumed all by itself right away,
though it didn't seem to hang this time. Here are the messages it
produced:
sio2: unload,gone
Return IRQ=10
Slot 0, unfielded interrupt (0)
Card disabled, slot 0
resumed from suspended mode (slept 00:00:01)
Card inserted, slot 0
Entire system suspend failure: errcode = 96
Now here's the clue. I can make it fail like that reliably when the
AC adapter is plugged in. But if I unhook the AC so that it's using
battery power, suspend/resume works perfectly every time! Plug in the
AC, and it fails again. Unplug it, and it works again.
What do you think about that? :-)
