I don't remember exactly what I did, but for some reason I guessed it might happen a second time, so I set the console to a text mode terminal before it happened the second time (since Linux doesn't give Blue Screens of Death otherwise). This is with an Adaptec 1480 card, AIC7xxx driver. I wish I had a wooden table so I wouldn't have to read and type this stuff back in by hand. (In case anyone here doesn't read thedailywtf, ignore the part about the wooden table. I still wish I wouldn't have to read and type this stuff back in by hand.)
