Probe message of APM driver when you #define APM_DEBUG in apm.c apm0 on isa apm: APM BIOS version 0101 apm: Code32 0xf00f0000, Code16 0xf00f0000, Data 0xf0000400 apm: Code entry 0x0000d003, Idling CPU disabled, Management enabled apm: CS_limit=ffff, DS_limit=ffff apm: running in APM 1.0 compatible mode apm: Slow Idling CPU disabled Also various Add hook messages &c. : Add hook "system keyboard" Add hook "default suspend" Add hook "default resume" called apm_event_enable() > 2. Result of apmconf and apm when you add "options FORCE_APM10" in > your kernel config file. There's a typo in apm.c that prevents this from working initially, you've used 'kcd_apm.kdc_description' (that should be kdc_apm...) # apmconf # apmconf -e APM ioctl: cmd = 0x20005005 called apm_event_enable() Unknown Original APM Event 0x10 Unknown Original APM Event 0xf Unknown Original APM Event 0xe Unknown Original APM Event 0xd Received APM Event: PMEV_NOEVENT (...repeats at about 1 sec interval...) Note that if I say # apmconf -d # apmconf -e after this, the 'Original' events don't reappear. Also, if I have APM disabled, close the lid, open it and then enable it, the system goes into sleep mode and then comes back out again straight away. If I try this : # apm I get this : APM ioctl: cmd = 0x40185002 Fatal trap 12: page fault while in kernel mode (blah) Note that the instruction pointer doesn't appear to be in the kernel, it's 0x48:0xc43e, which I'm presuming is in the APM bios. The 'fault virtual address' is 0xfd45. Disks still sync OK, but the machine doesn't reboot cleanly (wedges during BIOS startup) Anything else I can offer? I'll have an Accton 2002 to test in the next couple of days, but I expect it'll be a painless exercise. 8) > HOSOKAWA, Tatsumi E-mail: hosokawa@mt.cs.keio.ac.jp -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
