Very Computer

We have 2 E420s that, starting around Christmas, started to randomly
(though usually Fridays and Mondays) go into what appears to be
suspend mode.  Sometimes they even appear to recover by themselves.

I've verified that powerd is not running, that S85power has been
renamed to s85power, and that the power.conf has "noautoshutdown".
The actual packages for Power Management are installed.

We are running with raptor video cards, hme and qfe.  The only change
that occurred to the raptors at around that time was an addition to
/etc/system to force the hme and qfe to 100-Full.

# Set quad NICS to 100/Full

set qfe:qfe_adv_autoneg_cap=0          
set qfe:qfe_adv_100T4_cap=0
set qfe:qfe_adv_100fdx_cap=1
set qfe:qfe_adv_100hdx_cap=0
set qfe:qfe_adv_10fdx_cap=0
set qfe:qfe_adv_10hdx_cap=0

# Set quad NICS to 100/Full - END

# Set internal NIC to 100/Full

set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0

# Set internal NIC to 100/Full - END

Has anyone heard of anything like this? or have any ideas on what
direction to go with the troubleshooting?

thanks in advance,
