My Indy (CMN B006Y87, R4400 175MHz CPU) panics on the r4k-ip22
package shortly after boot:

[17179627.388000] Kernel panic - not syncing: Fatal exception in interrupt
I hadn't previously tested the 2.6.25 package in sid, but it appears
to do the same. I seem to be running fine on 2.6.18-6-r4k-ip22 from
etch however (with up-to-date sid userspace), so I'm less inclined
to suspect bad hardware. Let me know if you want the full dmesg or
anything...
