I'm still seeing a "fatal trap 18" in BETA4 on amd64. When I compile a custom kernel without device ataraid (otherwise same as GENERIC) that kernel boots fine. I'm including a trace, show reg, as well as the dmesg. What else can I do to track this down? ad0: 28620MB <ExcelStor Technology ES3230 ES7CA24G> at ata0-master UDMA66 Fatal trap 18: integer divide fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x8:0xffffffff802307da stack pointer = 0x10:0xffffffff809e8940 frame pointer = 0x10:0xffffffff809e89a0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) [thread pid 0 tid 0 ] Stopped at ata_raid_promise_read_meta+0x9a: divq %rsi,%eax db> tr Tracing pid 0 tid 0 td 0xffffffff8081ec00 ata_raid_promise_read_meta() at ata_raid_promise_read_meta+0x9a ata_raid_read_metadata() at ata_raid_read_metadata+0x29b ata_raid_subdisk_attach() at ata_raid_subdisk_attach+0x27 device_attach() at device_attach+0x292 bus_generic_attach() at bus_generic_attach+0x18 ad_attach() at ad_attach+0x37e device_attach() at device_attach+0x292 bus_generic_attach() at bus_generic_attach+0x18 ata_identify() at ata_identify+0xe6 ata_boot_attach() at ata_boot_attach+0x42 run_interrupt_driven_config_hooks() at run_interrupt_driven_config_hooks+0x2a mi_startup() at mi_startup+0xd3 btext() at btext+0x2c db> show reg cs 0x8 ss 0x10 rax 0x37e65da rcx 0x267 rdx 0 rbx 0 rsp 0xffffffff809e8940 rbp 0xffffffff809e89a0 rsi 0 rdi 0xffffff001e40ac00 r8 0 r9 0 r10 0x4 r11 0x1 r12 0xffffff001d532520 r13 0xffffff001e677800 r14 0xffffff001e40ac00 r15 0xffffffff80805440 ata_raid_arrays rip 0xffffffff802307da ata_raid_promise_read_meta+0x9a rflags 0x10246 dr0 0 dr1 0 dr2 0 dr3 0 dr4 0xffff0ff0 dr5 0x400 dr6 0xffff0ff0 dr7 0x400 ata_raid_promise_read_meta+0x9a: divq %rsi,%eax db> dmesg: OK boot kernel.GENERIC /boot/kernel.GENERIC/kernel text=0x553188 data=0xad050+0xdd480 syms=[0x8+0x8e7b8+0x8+0x76856] \GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2005 The FreeBSD Project.
