FreeBSD 4.9 freezes

[Jesse A. Coddington]

Hello,

Recently I purchased the D865GLC motherboard.  The computer has an Intel
D865GLC motherboard, 3 - Crucial 512MB PC3200 DDR, 4 - 75GB Western Digital
Raptors, and an ICP GDT8546RZ SATA Raid card.  I've installed FreeBSD 4.9
and everything works fine for about 15 to 20 minutes and then the system
freezes.  I've tried disabling Hyper Threading thinking that this may be the
problem, but the problem still exists.

Has anyone seen this problem before and if so, is there a solution?  If no
one has seen this problem, I'm open to resolve this issue.

Thank you,
Jesse A. Coddington
