[8-current] kernel panic at usbd_get_page+0x59 with uaudio

[MIHIRA Sanpei Yoshiro]

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.
