Kernel panic during boot in usb_add_task
I tried my brand new HP Compaq laptop 6710b under DragonFly, but during booting
the installer CD it "throws" a page fault:
uhub0: 2 ports ...
uhub0: <Intel UHCI root hub, ...>
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc04a9c5c
stack pointer = 0x10:0xc25f8d38
frame pointer = 0x10:0xc25f8d48
code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gram 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = Idle
current thread = pri 46 (CRIT)
kernel: type 12, code=2
stopped at usb_add_task+0x4c: movl %edi,0(%eax)
This happens with the latest snapshot version as of yesterday and also with the
FreeBSD 7.0-BETA3 silently hangs during boot, while NetBSD 4.0RC_4 works like a
charm (it can even dual-boot windows natively)!
There exists a thread on dragonfly.kernel named "Kernel panic during boot in
usb_add_task" about this issue.
