Me too, I have a very busy web server using 3 fast IBM disks as a CCD
and I'm not seeing any lossage since the new driver went in, thanks people,
but I've seen certain motherboard/bios/card combinations cause what Ted is
saying. I'm using an Intel Triton motherboard and its not given me
any problems [touch wood] since I installed the new 2940 driver. I'll soon
be building the "GodMother" of all Internet servers using this motherboard.
Multiple ethernet, SCSI and stuff :-) I'm going to publish instructions
on how to do all this, from what components to buy, to performance issues
and [as soon as I've done it] scalability issues. It should make good
reading.

Regards,
Neil.
