Hello people,
I wanted to record my favourite Simpsons series from TV via my ATI TV wonder card. It works fine automatically, no X needed, just framebuffer (nuppelvideo 0.4, nuv2divx, v4lctl from xawtv). I wanted to have my machine suspended when waiting for the recording to spare some trees.
There is setting in a bios for turning on interrupts which should cause wake-up. I turned interrupt 8 on. I modified code from linux/Documentation/rtc.txt To set alarm to some time. Then I tried 'apm -S' or 'apm -s' and waited. Unfortunately it doesn't work. When I wake it up by mouse later, the modified code from rtc.txt gets the interrupt and finishes fine. But it doesn't wake up itself by RTC interrupt :(
I also tried to turn on kernel compile flag which enables interrupts when calling APM bios but it didn't help.
I suppose it's a bios bug, so probably I can't do anything with it.
Anyone tried this successfully? Should it work? Can using ACPI instead of APM help me with this?
I've got Soyo 6VBA133 motherboard (Slot1) with VIA Apollo 133 chipset, Celeron 900. Kernel 2.4.12.
Thanks for any helpful reply.
Frantisek
