I've had three panics in the last two days. Oddly enough they have all been while I'm at the office (as opposed to home). The only difference being a different wireless lan. I have attached the three backtraces. I've no idea if they are enlightening in any way. I was simply hoping 1) someone might comment and point out anything that is wrong 2) maybe these could point to something that should be fixed before release? iirc, one happened on boot, one on shutdown, and one while my screensaver was up. uname -a FreeBSD fangorn.nxdomain.org 7.0-BETA3 FreeBSD 7.0-BETA3 #0: Thu Nov 22 11:26:35 CST 2007 If there is anything else I can provide please let me know.
