current on evbmips

Has anyone tried running -current on some evbmips hardware?
I tried on a an alchemy based board and failed - now trying
to narrow down
the problem.

It looks like something in interrupt handling is broken - I
get an "endless"
interrupt recursion on INT 5 (used as clockintr), these two
lines repeat
in the backtrace untill the kernel stack overflows:

cpu_intr+bc (83fff000,375,0,8000) ra 80275b94 sz 56
mips32_KernIntr+84 (f801,b4004104,104,4) ra 8028b3d8 sz 128

(ipending = 0x8000: MIPS_INT_MASK_5)

Any hints where to look?

With some patches from Andrew, my RouterBOARD 153 with
Atheros NIC is
not hanging early during boot, however, I got this LOCKDEBUG
panic before
I got a login prompt:
