That is.. it was until I typed 'make -j4 world': lock order reversal 1st clk last acquired @ ../../alpha/alpha/clock.c:569 2nd 0xfffffc00006ce728 smp rendezvous @ ../../alpha/alpha/mp_machdep.c:605 3rd 0xfffffc00006d9870 clk @ ../../alpha/alpha/clock.c:390 [hang] This is with alpha.smp.patch, plus the stuff recent commits. I had to change some #idef's into #ifdefs in alpha/trap.c though.
