OK, I take it back. I don't think it is a signed versus unsigned issue, though I still think it is dangerous the way atapi_read mixes them. I've been trying to follow the two pr's (kern/31530 and kern/31460) to see if the panics they're getting were related to the problem I reported earlier. It doesn't look like I am having the same kind of bytecount corruption problems reported in those pr's -- at least I'm not getting way large bytecounts. What seems to be happening is an atapi_read is partially completing and then an ATA_S_ERROR comes back on the status flag and this somehow leads me to an error message. Is anyone else, delving into this? And are there good places to read up on the specs for atapi-dvd-roms so I can make more sense as to how the drive should behave? - -r ------- End of forwarded message ------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
