Hi!

Thanks, seems your patch did the trick (panic gone). Following is dmesd:

apm_probe: APM bios gave zero len code16, pegged to 64K
apm_probe: APM bios gave zero len data, tentative 64K
apm0: <APM BIOS> on motherboard
apm: APM BIOS version 0102
apm: Code16 0xc00f0000, Data 0xc00fdfa0
apm: Code entry 0x00008010, Idling CPU enabled, Management enabled
apm: CS_limit=0xffff, DS_limit=0xffff
apm: Engaged control enabled
apm: found APM BIOS v1.2, connected at v1.2
apm: Slow Idling CPU enabled
Add hook "default suspend"
Add hook "default resume"

Sincerely,

Maxim
