on .10, I can run venti/venti. on .11, it locks up 9vx quite thoroughly after it prints init.... If you resize the window it is filled with garbage. Under strace I can see it taking the timer interrupts.
Linux xcpu 2.6.25 #6 SMP Tue May 27 09:46:16 PDT 2008 i686 i686 i386 GNU/Linux Sorry I don't have much more. I'm still looking around. also, on .10, when I am doing a venti/copy, at some point vx dies with a sigsev on cpux, where x is 5 or 7 or 9 so far. ron
