I see a similar, and completely repeatable error when booting 2.6.3-rc2, which 
didn't happen under 2.6.3-rc1 with the same .config.  Motherboard is ASUS 
P4GX8, kernel built for the P4, and this boot was with ACPI=off, which kept 
the console from constantly emitting '$' characters, which allowed me to 
capture the dmesg.  After booting, I also see only shifted punctuation keys 
(like > instead of .), and the shift key on my keyboard doesn't work.  The 
shift lock does make letters uppercase.  Section of dmesg follows.
