I get the following (copied by hand, hopefully no typos): db> trace 0 mi_switch(c05bdfc0,4c,c0316220,c05bdfc0,0) at mi_switch+0x210 msleep(c0acb2c4,0,4c,c05dce9f,1) at msleep+0x484 ad_attach(c0acb2c4,1,c14d47c0,c058fef0,c06f7d80) at ad_attach+0x21b ata_boot_attach(0,6fc000,c06f7d80,c03220ba,0) at ata_boot_attach+0x186 run_interrupt_driven_config_hooks(0,6f4000,6f4c00,6f4000,0) at run_interrupt_driven_config_hooks+0x2b mi_startup() at mi_startup+0xb5 begin() at begin+0x2c db> Is that any help?

Had the same kind of bug on a quite old motherboard with an intel controller : atapci0: port 0xffa0-0xffaf at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 Kernel and world are a bit older : FreeBSD cragganmore.lacave.local 5.1-BETA2 FreeBSD 5.1-BETA2 #0: Thu May 22 16:18:16 CEST 2003 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/CRAGGANMORE i386 (The bug did happen with the first boot on the generic kernel.) Currently, I run it in PIO mode ; the machine is in use, I can't afford much downtime. If I can provide other information with the machine running, I'd be glad to help. > Thanks > Nicolai Fred Who had forgotten about this bug... :) -- And you run and you run to catch up with the sun, but it's sinking And racing around to come up behind you again The sun is the same in the relative way, but you're older Shorter of breath and one day closer to death (Pink Floyd, Time) ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"

This looks strange, I dont have semilar HW here to verify the problem so I'm a bit in the dark. Is it possible you can build a kernel with ddb in it so we can get a traceback of the panic ? -Søren ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
