Did you apply the iicbb patches to your kernel? My dump is similar but the
call works:
11090 pvr250-setchannel NAMI "/dev/cxm0"
11090 pvr250-setchannel RET open 3
11090 pvr250-setchannel CALL ioctl(0x3,SERIAL_SETINVCLK,0xbfbfea2c)
11090 pvr250-setchannel RET ioctl 0
11090 pvr250-setchannel CALL ioctl(0x3,BT848_GAUDIO,0xbfbfea28)
11090 pvr250-setchannel RET ioctl -1 errno 6 Device not configured
11090 pvr250-setchannel CALL writev(0x2,0xbfbfe1b0,0x4)
11090 pvr250-setchannel GIO fd 2 wrote 58 bytes
"ioctl( tfd, BT848_GAUDIO ) failed.: Device not configured
"
11090 pvr250-setchannel RET writev 58/0x3a
11090 pvr250-setchannel CALL ioctl(0x3,BT848_SCAPAREA,0xbfbfeb40)
11090 pvr250-setchannel RET ioctl 0
11090 pvr250-setchannel CALL close(0x3)
11090 pvr250-setchannel RET close 0
11090 pvr250-setchannel CALL exit(0x1)
