Hi.
I use 8-current(csup-ed today) and uaudio device.
I record FM radio with below line.
/usr/local/bin/wavrec -d /dev/dsp0.0 -x -t 10 -S -s 48000 test.wav
kernel panic at usbd_get_page+0x59.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id=00
fault virtual address =0xc0
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc07997c9
stack pointer = 0x20:0xe64b1bcc
frame pointer = 0x20:0xe64b1bd4
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL =0
current process = 15(usbus0)
thread pid 15 tid 100035 ]
stopped at usbd_get_page+0x59; addl 0(%ebx), $eax
Is this known problem?
source tree which was csup at June/13/2009 was no problem.
Cheers.
