[-- Attachment #1 --] I have a Compaq Presario 2178EA and am upgrading from 5.2.1-RELEASE to -CURRENT. ACPI in 5.2.1-RELEASE seems to work OK, but with the new kernel I get a fatal trap on boot when ACPI is enabled just after the hard disk is probed; details below. Since there's a lot of information to give here, I've put a copy of the ASL and a verbose boot log with ACPI both enabled and disabled up at http://shrike.submonkey.net/~setantae/acpi/ - I'll happily try various values of debug.acpi.disable if someone can give me a pointer which ones to start with. For the archives, the trap is: GEOM: Configure ad0s1, start 32256 length 15035779584 end 15035811839 GEOM: Configure ad0s2, start 15035811840 length 14966396928 end 30002208767 ata1-master: pio=0x0c wdma=0x22 udma=0xffffffff cable=80pin ATAPI_RESET time = 17040us Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x3c fault code = supervisor read, page not present instruction pointer = 0x8:0xc04b5dea stack pointer = 0x10:0xc0c21c84 frame pointer = 0x10:0xc0c21cdc code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) [thread 0] Stopped at ata_generic_transaction+0x6a6: testb $0x1,0x3c(%eax) db> tr ata_generic_transaction(c159e708) at ata_generic_transaction+0x6a6 ata_start(c14f1200,c14f1320,0,c07e1e01,57) at ata_start+0x17b ata_queue_request(c159e708,c,0,c,8) at ata_queue_request+0x185 ata_controlcmd(c14f12a8,8,0,0,0,0) at ata_controlcmd+0x80 ata_identify_devices(c14f1200) at ata_identify_devices+0x150 ata_boot_attach(0) at ata_boot_attach+0x27 run_interrupt_driven_config_hooks(0,c1ec00,c1e000,0,c0441325) at run_interrupt_driven_config_hooks+0x18 mi_startup() at mi_startup+0x96 begin() at begin+0x2c db> Ceri -- It is not tinfoil, it is my new skin.
