That should give you good information on the status of the drives and any problems they have encountered. Smartmontools reports no problems with the drives; the system doesn't appear to be over heating at all. A bit more investigation shows it's panic'ing with privileged instruction in non-priviliged mode in what appears to be lseek(). This may or may not be related to the DMA TIMEOUT problem as I didn't see any timeouts before any of the panics I've witnessed. A bit more reading around suggests that the timeout issue is strongly related to my SI3112 SATA controller so I'm thinking of changing it; can anyone please recommend an SATA controller they're using which hasn't given them any problems? (Even better if they have Maxtor drives hanging off it!) I am also attempting to upgrade my system to a newer cvs but unfortunately I can't buildkernel on it - it'll either panic or generate enough timeouts to make make fail. If anyone could point me at a HOWTO or similar on cross-compiling then I'll compile it on my other machine instead (2xP3-1Ghz vs my desktop being an Athlon XP 1700+). All help appreciated as currently my desktop is becoming unusable and I fear for the safety of my data with the sheer number of panics being generated by disk use :) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: FreeBSD 5.3 freezes under heavy hdd load
I'm encountering a similar problem where my desktop system will freeze up and I'm wondering if something to do with the disks is the problem. I have two Maxtor Diamondmax 160 SATA drives on the same SATA PCI card, one of which is the home to FreeBSD 5.3 and the other is NTFS from my Windows XP install (which I'm migrating away from, hooray). The system hasn't frozen while I've been sat at it, only while it's been left to itself. Sometimes it's doing stuff (once was extracting Firefox for a portupgrade), sometimes it's not (being left overnight doing nothing in particular). Either way it freezes and has to be reset. While rebooting, it often complains about /usr to the extent that it wants me to manually fsck it before the boot will complete. It's always /usr. What makes the disk the suspect is log messages saying there's a timeout on the disk and it has two more retries, from which the machine usually continues. Unfortunately because of the freezing I can't see if that's happening when it dies. I would post some actual log messages but I had to leave it dead this morning due to lack of time to bring it up :) Tonight I'll check it's not overheating but I don't think that's the case - this machine doesn't usually run hot. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
FreeBSD 5.3 freezes under heavy hdd load
Hello, from time to time my FreeBSD freezes under heavy hdd load and only a hard reset will bring it back to life with fsck complaining about 'Softupdate Inconsistencies'. I had this behaviour on 5.3-RELEASE, 5.3-RELEASE-p5 and now i have it on 5.4-PRERELEASE. I am using a custom kernel with SMP enabled on a P4 3.2GHz for hyperthreading. One hdd is a SATA drive and it acts fine. The other hdd however is an ATA133 drive and i suspect it to be the problem, since freezes only occur when it is busy (eg. copying much data from a DVD/HDD to it or compiling a port). Whenever the system freezes there is no warning or log entry at all. I used 'smartmontools' to check the drive, but there was not found anything and the hdd appeared to be fully operational. Could the freezes come from a faulty IDE hdd (which would mean that I better get rid of it), or are there other possiblities.

I had similar issues on an Athlon machine under 5.3. In my case it turned out that the CPU was running extremely hot. It would frequently freeze while portupgrade was backing up old versions of a port. I initially suspected a disk problem as well, but I haven't yet had any problems since cleaning my CPU and chipset fans. On reflection, my freezes were probably due to the CPU running hotter than usual when running bzip2 (which I believe is how portupgrade stores its backups, and is very CPU-intensive). It is possible that your drive is the culprit, but you would probably get console messages about I/O failures rather than just a hard freeze. Flaky memory or power supply are also possibilities.

It is necessary to increase KSTACK_PAGES (e.g. to 4) on machines with certain patterns of heavy disk write load to avoid double faults in the softupdates code (softupdates has potentially unbounded call stack and can overflow the default kernel stack size without too much effort). This would cause panics though, not freezes.
