The following reply was made to PR kern/23411; it has been noted by GNATS. From: "Hiten Pandya" <hitmaster@mysun.com> To: freebsd-gnats-submit@FreeBSD.org Cc: shon@misproductions.com Subject: Re: kern/23411: SMP Kernel Freezes Machines on Dual Processor TYAN Tiger Motherboard System. Date: Mon, 21 Jan 2002 15:04:30 GMT This might not be the solution, but it can get rid of bugs in your kernel configuration. According to the kernel config file you submitted, it seems that there is a minute un-noticeable error (to my eyes anyway): 01: machine i386 02: # cpu I386_CPU 03: # cpu I486_CPU 04: cpu I586_CPU 05: cpu I686_CPU If you notice, on line 04 and 05, you can only have one type of processor I beleive. According to the way SMP works, on intel, you can't mix and match CPU types. I would say, that you look at your dmesg output and see what type of processors you have (it should be an i686 neway). Either way, you should only have one CPU type in the kernel config file, i.e. you need to comment out either 586 or 686 in your kernel config file. cpu 1686_CPU This technique worked on my system, which is : VIA Apollo Motherboard, (Gigabyte) 2x 933MHz Pentium III (i686) In addition, you can also have a look at the various options available for the different CPUs, and motherboard limitations. You could also send me your dmesg(8) output, and I will try to analyse it, if the above solution doesn't work. (my email address below) One last thing, also enquire if there are any other options in your kernel config file, which conflict with the SMP options, or with any other options. (these should be documented in the LINT file.) regards, Hiten Pandya <hiten@uk.FreeBSD.org> <hitmaster@mysun.com> Security Fingerprint: 45 a5 9c f2 fb 07 da 70 18 02 0b f3 63 f1 7a a6 hitenp@hpdi.ath.cx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
