A failure report unfortunately :(

I did a fresh install of the 201103090800Z daily build on a Sparc 20
with dual SM51 CPUs and have seen two panics so far. The first one,
the dma0 error, happened when unpacking a gzipped tar file and the
second, tp->t_lastm, when compiling Tcl 8.5.7. Console capture is
included below.

I don't know if it matters but the two SM51s are not identical, CPU0 is
a 501-2607 and CPU1 is a 501-2352.

login: panic: dma0: cannot allocate DVMA address
