[Please CC me as I am a stable user and not on the -current list] I'm running stable on a box at home and wanted to check if the -current kernel fixed a problem with my CD-RW drive. So I downloaded the boot floppies from current.freebsd.org, the 20010419 snap (which John B. tells me installs OK on his system). I disabled nearly everything from the visual config, then quit from that. It got as far as PnP detection then failed with an integer divide fault. The following was on the screen (copied by hand!): sio0: configured irq 4 not in bitmap of probed irqs 0 sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 8250 sio1: configured irq 3 not in bitmap of probed irqs 0 vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0 unknown: <PNP0303> can't assign resources unknown: <PNP0f13> can't assign resources fatal trap 18: integer divide fault while in kernel mode instruction pointer = 0x8:0xc03085f5 stack pointer = 0x10:0xc080671c frame pointer = 0x10:0xc0806768 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor flags = Interrupts enabled, IOPL = 0 current process = 0 (swapper) trap number = 18 panic: integer divide fault I've attached a dmesg from a verbose boot of 4.3 on the same hardware. If there is any other info I can provide, please yell. Greg.
