Sometimes 4 times in one hour. Reset button is the only solution, no Ctrl-Alt-Del, no Ctrl-Alt-Esc (DDB is compiled in the kernel and "usually" works). This box has been fairly stable for a couple of months of production mode, although it did experience a shorter series of similar hangs (2 or 3) a few of weeks ago. I have switched the disk to a completely similar box (same m/b, configuration...) and it also hangs, so I have more or less ruled out a hardware failure (unless the disk is the culprit?). Does it ring any bells ? A search on this failed to produce any close result. All critical patches to 4.5 mentioning system crashes found on the "Errata" section of www.freebsd.org have been applied, at least all the ones relevant to a machine with no shell users. Kernel is non-SMP. Configuration: ASUS P4T-E m/b CPU: Intel P4 @ 1.6Gb Memory: 512Mb in one DIMM (or whatever this kind of memory is called) Disk: IDE Seagate ST340016A 38 Gb Video: old PCI S3 ViRGE adapter (always in text mode) Oh well, why not copy/paste dmesg to provide real info?
