PROBLEM: 2.6.13 crash on sparc64 in sunsu_kbd_ms_interrupt

[Jim MacBaine]

1. 2.6.13 crash on sparc64 in sunsu_kbd_ms_interrupt

2. I'm running 2.6.13/sparc64 on a diskless Sun Ultra 5 workstation.
After an uptime between 5 and 20 minutes after start, the kernel
crashes, system stalls.

3. sparc64 sun keyboard sunsu_kbd_ms_interrupt

4. vanilla 2.6.13

5. Last working kernel version is not known. 2.6.12.5 shows the same behaviour.

6. Kernel message is attached to this mail.

8.5. lspci -vvv output attached

The kernel has been cross-compiled on a x86 Linux system, and
converted from ELF to a.out format in order to boot it via network.
