I think you have a hardware problem somewhere :( I've tried it on my home machine and failed to reproduce also. However it is strange, because if it is the CPU/Memory problem, then there should be other signs - random applications crashes, spontaneous reboots etc., but machine is pretty stable - up and running for weeks since 4.0-REL w/o any notable problems. On the other hand if it is HDD problem or problem with its cable, then there should also be some signs. I've never seen this problem on the same hardware under 2.* and 3.* during past 1.5 years. Maybe it is ata driver, because it is the only thing that is known not very extensively tested (and has already acknoweleged problems with some hardware). I'll try to fallback to the wd and look what will happen. -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
