That will give us a clue as to what is going on. Uncommenting the existing RISC_COUNT and INT_STATUS print, I was lucky and it happened almost immediately after starting fxtv the first time after booting the debug kernel (compressed output attached). > cut -c41-45 messages | sort | uniq -c 233 0206 353 020e 111 0a04 44 0a0c 1 1206 1 3206 2 3286 98 3a04 15 3a06 4 3a0c 1 420e Your and Steve's eye will doubtless glean more than mine, but the events that look "unique" to my untrained eye are the: 18:52:36 stealth /kernel: bktr0: ioctl: tsleep error 35 100052c error in the middle, the single FIFO Data Stream Resync in the INT_STAT values (xxxx420e above), and the Luma/Chroma ADC overflows (xxxxxxx8) that don't set in until a good way down the output, and then stick in there for the rest of it.
