[A version of the below has been submitted to bugzilla as 214598. The specific powerpc64 context is a PowerMac11,3 PowerMac G5 "Quad Core" --actually 2 sockets with each having 2 cores.]
The failure was: "panic: vm_fault: fault on nofault entry, addr: c000000000022000" Details. . . I manually entered ddb and gave it the dump command. 2 of 3 chunks worked. This is new since last I tried (long ago): it used to be it complained about the DMA request size being too large. (I've not tried in a long time, under some 10.<?> .) So this got a lot farther than I've ever seen before for this type of context. Transcribed from a camera picture of the screen. . . (Typos?) (Also: I will drop off various leading zeros and some formatting will be different.)
