We have a 2400A in a heavily loaded 'backup' machine at the office (i.e.
lots of large IDE drives, storing backups from all the other machines until
they're spooled to tape) - it's often gzip'ing and storing the data from
several machines simultaneously, all across a 100Mbit LAN.
We've never [touch wood] had any problems with it so far...

I'd be a bit concerned if any machine I'd been using, ever actually had to
shut itself down for thermal reasons [unless it was, actually faulty].
Remember - weird things can happen before it gets to the 'critical' level
set by the motherboard [unless it's been set really, really pessimistically
in the BIOS].

I'll agree - I don't particularly like the 2400A - we have a bunch of 3ware
controllers as well, which seem better supported in FreeBSD, and 3ware
themselves seem to be more open-source/OS friendly, but we've never had any
real problems with the 2400A.

The hardware we have it on here is a lowly ASUS K7VML, running FreeBSD
4.8-STABLE w/784Mb of RAM. The CPU is an AMD Athlon 2000.
I can post you it's dmesg output off list if that might be remotely helpful
- but just to let you know, there is at least the odd 2400A based system
out there running under heavy load :)
