I'm not too familiar with the locking architecture on FreeBSD, so this is probably my fault... I've been meaning to take a look ainto this for some time now, but something more pressing always manages to come up everytime I have some free time... Since I don't know too much about the way mutexes are done on freebsd, I would really appreciate it if somebody could hand me a definitive guide on mutex and locking on FreeBSD, or point out what I should be looking at in the source... Or better yet, look through dec/pccbb and tell me what I did wrong and how to fix it... As far as the suspend problem, I can't seem to reproduce it on my laptop (IBM 600E), otherwise I'd try to hunt it down. I don't know, but computer problems seem to have a way of resolving themselves automagically whenever I am in the general vicinity... -Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
