Under 2.4.2 heavy I/O would wedge one of the CPUs (a nice watchdog message manages to plaster itself on the console, very BSOD-esque).  Once one of the CPUs stuck it was usually a VERY short period until the other CPU lost itself waiting for the wedged CPU to release it's lock.  I don't know if this effects IDE machines (I don't have any), but I couldn't stay up for a day if I started PostgreSQL/Informix, or if I really hit Squid.  I moved from my BusLogic BT-950 to an IBM ServerRAID card thinking (at first) that it might be an iffy card.  The IBM easily doubled my I/O throughput and halved my average uptime.  Been using 2.4.3 for several days now with nary a glitch.  I even did a "update statistics low drop distributions; update statistics high" in Informix, which basically causes a sequential read of every table in the database (roughly two million records and corresponding indexes), and my box is still up.

I'm trying,  but that takes time. :)  Actually they already said they will try and provide a speaker, but I expect Seawolf will be old news by then.

Nah, I got that too.
