I wish FreeBSD 5.3 was as stable as the STABLE tree implies it was. My SMP problems are quite numerous on 5.3 so far.Hi,
I wasnt quite sure what to call this problem.
I am running FreeBSD 5.3 STABLE on a quad Pentium Pro IBM Netfinity 7000 system, and since the GENERIC kernel does not come SMP enabled I compiled a kernel with SMP support and drivers for networks card and SCSI RAID adapter built into it (not loaded as modules). This build happens fine under the original GENERIC kernel.
Afterwards, since that machine is quite powerful and its destined to be a unix server I wanted to compile a kernel for another box I have. I wrote the kernel config file, and started the compilation. At some stage the system crashed, on the console it looked as though it had tried to reboot itself (3 times!) with various messages about CPUs ignoring requests. I dont really understand why under the SMP kernel I compiled the I cannot compile another kernel, but under GENERIC it works fine.
I can only think two things, either I have stumbled accross an odd bug or my hardware appears to be working fine on the surface and actually there is something slightly wrong, although this machine ran the GENERIC kernel of 5.2 for a long time without any issues (5.2.1 was SMP enabled from the start I believe).
I have a similar system to yours, but a dual processor. One thing I see is that as the days have gone by since the original 5.3-Release, the SMP code has had some code changes that have alternately caused crashes or compile-time errors, at least from my point of view. I am beginning to regret using 5.3, but all of the press releases nudged me to believe that 5.3 ws ready for live systems. I have to admit that I had problems with 4.7 and 4.9, but not like the 5.3-STABLE track. I hope all of this doesn't give FreeBSD a bad reputation, although it might earn it if it continues to be so buggy for SMP systems. Having no experience with 5.2, I almost wish I could provide more advice. But perhaps you can get the generic kernel off the CD and boot to it to recompile your kernel.
See this as one documented example: ftp://ftp.freebsd.org/pub/FreeBSD/ERRATA/notices/FreeBSD-EN-05:03.ipi.asc
My last cvs update was the 30th (yesterday) and it compiled for me using
make -j6 buildworld and took 3:38. My kernel build took 1:27. Those are with a working SMP kernel, so the generic kernel would take longer.
