[REGRESSION] 2.6.25 on parisc - CPU 1 is stuck

[Domenico Andreoli <cavokz@gmail.com>]

Hi,

  as soon as I booted my dual PA8600 with 2.6.25 I got 1 CPU less. The
only other kernel I successfully used on that box is Debian's 2.6.22-3.

Debian never built 2.6.23 for parisc, 2.6.24 was still hanging last
time I checked it, 2.6.25 did not even build until recent -rc. So I am
not in the best position to bisect.

Here is the relevant dmesg.

Cheers,
Domenico
