The led flashes. Hmmm, the CLI call is not useful in this case... I also had another kind of problem about CLI, my box froze sometimes when suspending. It shouldn't be put CLI in here as Nate mentioned. Segment regisers also wasn't related with the problem. I watched %fs before & after BIOS call using ddb, the value didn't change on my box. I guess Linux code only expects some BIOSes manipulate segment registers. Another possibility is *delay mechanism* on suspend (and standby). AFAIK, Linux, NetBSD and PAO has this but CURRENT. I'll make patch tonight based on PAO APM code. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
