The system boots fine with 5.1 RELEASE, but it hangs when using current.
It looks a bit like port-cobalt/44292, but I do not get any message after pid 
1(init): ABI set to O32 (e_flags=0x1007)
..

here the full dmesg and backtrace, once it hangs (do not worry about wd0 in 
raidframe.. I've my 5.1 release install on that disk and have not added it to 
the raidframe mirror so far):
