Grr, still getting used to mutt, and I didn't reply to the list. Yes, I'm using an SMP board, and waiting on the arrival of the 2nd processor. It boots up and runs fine. > Before pointing any fingers at softupdates, etc...

Yup, I've "fallen back to" a UP kernel, which hasn't crashed at all, and I've done the same thing (rm -rf, cvs update) many more times than were required to crash the SMP kernel. Before I try this again, I'll have a second processor in there.. - alex To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Well, it does work. Right now if we enable multiple CPU's with SMPng the machine instantly panics, so we use a sysctl that keeps all the extra processors waiting until we are ready to kill the machine. Until that point in time, however, the machine runs happily on 1 cpu, and can build world ok, etc. -- John Baldwin <[EMAIL PROTECTED]> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Personally, I'm astonished that an SMP kernel will actually boot and run on a uniprocessor machine. Before pointing any fingers at softupdates, etc... I think that the first thing I'd do on this machine is switch back to using a real uniprocessor kernel, and then see if I could replicate the problems. -- These are my opinions -- not to be taken as official Skynet policy == Brad Knowles, <[EMAIL PROTECTED]>|| Belgacom Skynet SA/NV Systems Architect, Mail/News/FTP/Proxy Admin || Rue Colonel Bourg, 124 Phone/Fax: +32-2-706.13.11/12.49 || B-1140 Brussels http://www.skynet.be || Belgium "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.

SMP and softupdates?
In upgrading my system I've bought a shiny new SMP mobo to go with my new 30gb Deskstar... The nice thing about this new board is my HighPoint HPT366 based IDE controller works now (Buggy Phoenix BIOSes prevented it from working before). Perhaps in a rush to get started, I've compiled and been using a SMP kernel even before the second processor arrives. This has worked fine, however I've gotten some rather weird hangs and crashes resulting in a nice lost+found directory on the usr fs. In trying to track this down, I've tried a UP kernel which seems to not have crashed where the SMP one did before.. I'm sure it's not a cooling issue as the sole CPU is staying below 35C. However I'm curious: * Are there any known issues with SMP and softupdates as of late? * Is running one processor with an SMP kernel such a horrible idea (other than performance wise)? I'm glad I can run my harddrives (Caviar and Deskstar) at ATA66 speeds.. but having to tread lightly is sucking. - alex To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
