Hi, 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... > For a while I've thought that it could be my system over heating. But > when my machine overheats it just powers off abruptly. 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 have been searching the groups and mail archives for almost a year now. > I can only find posts with similar problems but no resolution.

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. > if you managed to read through my ramblings.

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 :) Regards, -Karl
