Hi, I've been trying to use OpenBSD on an older (2009) Toshiba laptop but I am running into some difficulty with ACPI. What appears to be happening is that as soon as the \_PIC method is invoked inside acpimadt the machine usually just reboots (with the May 31st snapshot it now no longer reboots, but never proceeds past the acpimadt line in the dmesg).
To run OpenBSD on this machine it is necessary to disable acpimadt but this means that the machine effectively runs under a single core. Another option is to disable the invokation of \_PIC in acpimadt, and this seems to allow OpenBSD to pickup the two CPU cores, but this doesn't really seem safe. To make matters even worse, the BIOS on the machine seems to have 2 different DSDT ACPI tables. The good table has a creator id of MSFT and is almost twice as large as the bad table (which has a creator id of INTL). The machine starts with the good DSDT table, but at some point the BIOS will swap out the good table with the bad table. The actual DSDT memory is modified in SMI. If I debug the kernel, I can see that OpenBSD is starting with the good table but by the time I get into user space, acpidump dumps the bad DSDT table. Under Windows 7, the DSDT memory never seems to get modified and the BIOS is at least happy enough to not swap out the DSDT table during SMI. At this point, I'm hoping that someone more familiar with OpenBSD's ACPI implementation and AML can see something obvious in the DSDT table. I have some older dmesgs, acpidump output, and Windows 7 DSDT table on my website: http://devinsmith.net/toshiba/ Here is a dmesg from March with the \_PIC method disabled. I did try with the May 31st snapshot, but the machine locks with acpimadt as the last line printed.
