On a new Thinkpad T21 laptop running 1.5, I tried inserting a PCMCIA 
Maxtor hard drive.  When I do, the machine hangs.  It prints
"Stray interrupt on IRQ 7" (or words to that effect), followed by "wd2 
at pcmcia1 function 0".  It never comes back after that.  Hitting 
cntl+alt+esc makes it say "cardslot1 at cpu_Debugger+0x4 leave".

For what it's worth, Win2k likes the drive just fine, so it's not a 
hardware problem.
