Subject:   Problem with Serverworks HT1000 serial ATA support - Tyan S3992 Motherboard
Message-ID:  <579700.81808.qm@web34507.mail.mud.yahoo.com>

 Hello.
 I am testing out a new tyan motherboard that uses the
next generation of AMD chips and the Serverworks
Chipset. It seems that I can reliably crash it with a
simple bonnie++ test if I set:

/boot/loader.conf  - Used for DiskD for Squid
  kern.ipc.msgtql=2048 

 I am using FreeBSD 6.1-STABLE amd64. This all works
just fine on a non Serverworks Chipset Tyan Board.
(literaly I unplug the drive and move it to another
system and it works and works in production)


 If I run: bonnie++ -d /home -u root s1g
  The system reboots.

 I have tried this is both S-ATA and P-ATA emulation.

 Any ideas on why this setting, which works on non
Serverworks boards, would make the Serverworks so
twitchy?


  Thanks

  Nicole
