I'm investigating a problem I'm having (two kernel page faults so far an AMD64 on v6.0 release), possibly related to the bktr driver. At this point I'm just fishing for answers, because I haven't run the new system for a long time (installed Sunday). But, when I run my motion-activated recorder on two bktr devices simultaneously, the system dies within minutes. If I don't run them, the system is stable. I'm using Hauppauge WinTV Go + devices, if that helps, and capturing frames in RGB24 mode using METEOR_CAP_SINGLE in a tight loop with a tuner call to TVTUNER_SETCHNL on the associated tuner. If anyone can say "Yes, that is definitely a known problem, apply patch X" that would be great! :-) Or, "Don't use METEOR_CAP_SINGLE, it's unreliable", that would help too. Even just letting me know that you use bktr on an AMD64 with v6.0 and *don't* have problems would be useful... Otherwise, I'll be investigating the problem more this weekend. On a possibly related note, a few minutes before the first crash, one of my application programs (which has not crashed in 6 months) died with a SIGSEGV because a pointer it was using had the value 0x888f8d847c80817f, which is suspiciously "around 0x80" for every byte (I say "suspicious" because that could be RGB video data. It could be green cheese, too, for all I know, but... Coincidence?) Cheers, -RK -- Robert Krten, PARSE Software Devices +1 613 599 8316. Join us at BSDCan 2006!
