It can also be repeated when using large apps like mozilla or nautilus. This is one example, though it can also happen during intensive disk operations (this may be due more to IDE), so I'll look into this aspect later to see if there is a correlation when these lockups appear with disk operations while removing the IDE bottleneck aspect. These lockups are worrying for me because, they lead to system reboots. And they are my personal benchmark for stability (ie can FreeBSD recover or not when it happens). FreeBSD 5 RC-1 -> system reboots FreeBSD 5 RC-2 -> ok FREEBSD 5 RC-3 and RELEASE -> ok FREEBSD CURRENT (as of last weekend) -> system reboot. I'm back to RELEASE, because the constant reboots can cause data corruption which is not good for my one and only home system. --=20 Khairil Yusof --=-LRDZfzOG0DuLS4Y4zQ73 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQA+ZLMyDAqnLW/+/X8RAse4AKC2KQ07S+HIoyB7kFCykHhdDJ3sWQCg3d3P a+S7oSZ0Rna9H+gFyyfwrak= =Woll -----END PGP SIGNATURE----- --=-LRDZfzOG0DuLS4Y4zQ73-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
