I'm trying to install on a new motherboard ASUS M3N78-EM. While booting from FreeBSD installation CD I'm getting run_interrupts_driven_hooks: still waiting after 60 seconds for xpt_config This is repeated a few times then installation stops and the machine stops responding. I've tried various versions, including 6.4R, 7.0R 7.2R and 8.0-CURRENT-200905-i386-disc1.iso. I've also tried SATA mode and AHCI mode for the SATA controller. I get a panic from the 8-CURRENT snapshot. The others might be panicking but I guess their standard kernel doesn't have debug stuff Backtrace from 8-CURRENT (typed by hand). panic: run_interrupt_driven_hooks: waited too long cpuid=0 KDB: enter: panic [thread pid 0 tid 100000 ] stopped at kdb_enter+0x3a: movl $0,kdb_why db> bt Tracing pid 0 tid 100000 td 0xc0d88fd0 kdb_enter(c0c3d8cf,c0c3d8cf,c0c3feac,c1820d08,0,...) at kdb_enter+0x3a panic(c0c3feac,0,c0c3fe43,70,ea60,...) at panic+0x136 run_interrupt_driven_config_hooks(0,181ec00,181ec00,181e000,1825000,...) at run_interrupt_driven_config_hooks+0x1c7 mi_startup() at mi_startup+0x96 begin()at begin+0x2c db> ============================================================= After some trial and error the problem seems to be device sbp in the kernel config file. Comment that out and rebuild kernel and it boots. Here's a backtrace from 7.2R using a GENERIC kernel (with sbp enabled) with debug options added. run_interrupt_driven_hooks: still waiting after 300 seconds for xpt_config panic: run_interrupt_driven_config_hooks: waited too long cpuid=0 KDB: enter: panic [thread pid 0 tid 0 ] stopped at kdb_enter_why+0x3a: movl $0,kdb_why db> bt Tracing pid 0 tid 0 td 0xc0cc1b40 kdb_enter_why(c0b87110,c0b87110,c0b89425,c1020d0c,0,...) at kdb_enter_why+0x3a panic(c0b89425,0,c0b893c0,71,ea60,...) at panic+0x136 run_interrupt_driven_config_hooks(0,101ec00,101ec00,101e000,1025000,...) at run_interrupt_driven_config_hooks+0x1b7 mi_startup() at mi_startup+0x96 begin()at begin+0x2c db> >How-To-Repeat: Boot the motherboard with any of the standard kernels listed above. >Fix: Workaround: Disable firewire in BIOS Install from a standard CD Reboot to hard disk Build and install a custom kernel with device spb disabled Reboot and enable firewire in the BIOS. kldload sbp if required (I have tested that it loads, not whether it works.) >Release-Note: >Audit-Trail: >Unformatted:
