I have to ssh into the machine and kill XFree86. Ktracing it, I see: 651 XFree86 RET ioctl -1 errno 16 Device busy 651 XFree86 PSIG SIGALRM caught handler=0x80d4318 mask=0x0 code=0x0 651 XFree86 CALL sigreturn(0xbfbfe340) 651 XFree86 RET sigreturn JUSTRETURN 651 XFree86 CALL ioctl(0x7,0xc0286429 ,0xbfbfe680) 651 XFree86 RET ioctl -1 errno 16 Device busy 651 XFree86 PSIG SIGALRM caught handler=0x80d4318 mask=0x0 code=0x0 651 XFree86 CALL sigreturn(0xbfbfe340) 651 XFree86 RET sigreturn JUSTRETURN 651 XFree86 CALL ioctl(0x7,0xc0286429 ,0xbfbfe680) 651 XFree86 RET ioctl -1 errno 16 Device busy This seems similar to the problem indicated in this thread: http://marc.theaimsgroup.com/?l=freebsd-current&m=103401443626417&w=2 but not quite. It doesn't seem to correspond to any particular activity. This is the only machine I get it on, and I've tried multiple upgrades and rebuilding X and such. Any ideas would be much appreciated.
