I have experienced the following problem a couple of times in 2 different machines and FreeBSD versions (see below): when the disk is continuously reading/writing (like when copying/extracting a file, checking the filesystem in the background, etc.) my system crashes sometimes (it's not an everyday thing, but quite frustrating when it happens). When copying from another machine by NFS/SMBFS more than one file at the same time (or when using the disk, like described above) often crashes (and the disk light indicator turns off). Running "atacontrol ad0 mode UDMA100" when it was UDMA133 crashed the system (the disk activity indicator was always on) when I tried to solve the problem that way. Also when I was installing a port which installs many files on the second machine without using NFS/SMBFS, trying to mount a local NTFS filesystem (with kernel driver) crashed. The first machine is an Athlon XP 2400+ with FreeBSD 6.1-RELEASE and custom kernel (see below) and the second one a new Athlon64 X2 3500 with FreeBSD 6.2-RELEASE running in i386 mode, with generic SMP kernel. See the boot messages and kernel config here: http://people.freebsd.org/~alepulver/disk-crash.tar.bz2 Also I got (only twice, when checking the filesystem after one of these crashes) the following error on the first machine, that I don't know if it's related or not to the previous problems: fsync: giving up on dirty 0xc51d6990: tag devfs, type VCHR usecount 1, writecount 0, refcount 806 mountedhere 0xc51a4000 flags () v_object 0xc144cb58 ref 0 pages 3232 lock type devfs: EXCL (count 1) by thread 0xc54e2c00 (pid 837) dev ad2s1f I would appreciate any help. If you need more information just ask.
