I tried 5.3-STABLE with vinum and gvinum and had a number of crashes with
a Supermicro P4DC6 dual 1.8GHZ Xeon/512MB, RAID 1 boot device using the
Adaptec 2005S + onboard SCSI, Compaq OEM Adaptec 39160 (flashed to Adaptec
v 2.57 BIOS), 8 Seagate 43GB drives in a RAID 5 array.
I dropped back to 4.11-STABLE, same hardware, no crashes. I had two
processes copying 150GB from an NFS-mounted volume to the RAID 5 array for
On the other hand I'm running 5.3-STABLE on a Toshiba 8100 notebook and
dual PIII/Supermicro P6DGH which have been rock solid.
I personally would not use the 8139 Ethernet cards in a server (see "man

chipset is a horrible kludge. I personally use only Intel Pro100 and
variants (the P4DC6 has one built in).
(I can't tell you if the problems I had were hardware (I did change memory
