Hi there,
Since installing 2.2.5 on a few of my workstations, I have noticed
a very large number of crc receive errors with the de0 driver. Since this
upgrade, I am also no longer able to run the card in 100M Full duplex modes.
Attempting to set the card in such mode results in very large numbers of
the above mentioned crc receive errors. Another problem I have been having
is with network performance. I have a workstation dedicated to act as a
local tape server. First I was running 2.2.2 and then 2.2.5 with the same
problems. If I start a dump from a remote workstation, it takes *forever*
to complete, if it even gets that far. For example, I started a 2Gb dump
yesterday afternoon and it is *still* running this morning, having only
completed 40% or so. The tape drive is an Archive 4586 tape changer. The
controllers I have tried using with the same results are the adaptec
2940, 1540, and 2940UW. When I used an HP 2gb dat, I had none of these
problems. Dumps would complete in a relatively short period of time.
Suspecting the drive itself, I have switched it with 4 other 4586's
with the same results. Doing a dump on the workstation with the drive
results in somewhat quick dumps. Attempting to use tar also results in
very long times. If anyone could shed light on this problem, I would
be greatful. I suspect a lot of folks purchased these 4586's as they
were recently sold at a great price.
Regards,
Jeff
