I upgraded to RELENG_6, changed all HW (whole servers and changed Seagate HHDs to Samsung so every piece of HW is different from time of my first post), but after one week I got the same error and system reboot today: Aug 19 15:11:20 track ntpd[456]: kernel time sync enabled 2001 Aug 19 15:15:47 track kernel: ad6: FAILURE - device detached Aug 19 15:15:47 track kernel: subdisk6: detached Aug 19 15:15:47 track kernel: ad6: detached Aug 19 15:15:47 track kernel: GEOM_MIRROR: Device gm0: provider ad6 disconnected.

As other poster has different chipsets (ICH6 and nVidia), it seems more FreeBSD ATA driver related. (7 different machines was tried) Now after reboot, writing and reading from ad6 is really slow (no other processes utilizing disks, no fsck runnig etc.) root@track ~/# dd if=/dev/zero of=/dev/ad6 bs=1m count=100 100+0 records in 100+0 records out 104857600 bytes transferred in 43.673244 secs (2400957 bytes/sec) root@track ~/# dd if=/dev/ad6 of=/dev/null bs=1m count=100 100+0 records in 100+0 records out 104857600 bytes transferred in 10.979482 secs (9550323 bytes/sec) Is there anyone who can help with finding the source of problem? It is really annoying that one can not use SATA / ICH7 under high load in FreeBSD 6.1 (tested on RELEASE and STABLE) (I am not so HW / FreeBSD experienced to locate the problem by myself) Miroslav Lachman
