I copied a CURRENT kernel from a 200608 snapshot and the problem also occurs thus I'm adding current@. My current laptop doesn't have a serial port so I'm copying this by hand: Fatal trap 18: integer divide fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x20:0xc08a1fb7 stack pointer = 0x28:0xc0c20b14 frame pointer = 0x28:0xc0c20b9c 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 pid 0 tid 0 ] Stopped at __qdivrem+0x3b: divl %ecx,%eax db> bt Tracing pid 0 tid0 td 0xc0a0c818 __qdivrem(37fdfa0,0,0,0,0,...) at __qdivrem+0x3b __udivdi3(37fdfa0,0,0,0) at __udivdi3+0x16 ata_raid_promise_read_meta(c37a5000,c09f4a80,1,8086,c37a5000,...) at ata_raid_promise_read_meta+0x9b ata_raid_read_metadata(c37a5000,c37a5000,c0c20c70,c06b58a4,c37a5000,...) at ata_raid_metadata+0x2be ata_raid_subdisk_attach(c37a5000) at ata_raid_subdisk_attach+0x33 device_attach(c37a5000,c37a5180,c37a5000,c36885c0,0,...) at device_attach+0x58 device_probe_and_attach(c37a5200,c37a5200,c08ec9a9,0,c37a5180,...) at bus_generic_attach+0x16 ad_attach(c37a5200) at ad_attach+0x2c8 device_attach(c37a5200,c095f2d0,c37a5200,0,c368d800,...) at device_attach+0x58 device_probe_and_attach(c37a5200) at device_probe_and_atach+0xe0 bus_generic_attach(c3659080,c3659080,ffffffff,0,c37a5200,...) at bus_generic_attach+0x16 ata_identify(c3659080) at ata_identify+0x1c8 ata_boot_attach(0xc0a11d80,0,c09212e7,47,...) at ata_boot_attach+0x3e run_interrupt_drive_config_hooks(0,c1ec00,c1e000,0,c0451065,...) at run_interrupt_drive_config_hooks+0x43 mi_startup() at mi_startup+0x96 begin() at begin+0x2c This board has a Promise SATA raid controller and it is disabled in the BIOS.
