Distribution: Debian Unstable (Sid) 2004-09-20
Hardware Environment:
Sun Ultra Enterprise II
2x200 mHz UltraSPARC I Processor
512MB RAM
2x4.3GB 7200RPM SCSI Disc
Toshiba SCSI CD-ROM

Kernel configuration and dmesg output are pasted below for reference purposes.

Software Environment:
Standard Debian Unstable System

Problem Description:
Sun Ultra Enterprise 2 was hardlocking in 2.6.xx. Never responded to keyboard
input. Sometimes would respond to pings and SSH connections for a while, but
would always lock hard eventually with no errors. Note that this exact same
system works perfectly in 2.4.xx. I reiterate, SMP functions correctly there.
Obviously something has changed and caused functionality to break, hence why I
have marked this bug high severity. IMHO, "stable" kernel series should not
result in a step back in hardware compatibility.

Disabling SMP resulted in a working system.

Steps to reproduce:
Compile with the following kernel configuration, except add the SMP option.
Witness the machine fail to continue functioning.
