[Qemu-devel] PPC: Regression booting NetBSD

[Mark Cave-Ayland]

Hi all,

I've been running my OpenBIOS test suite on a recent git (commit a1d22a) 
and have encountered a QEMU process segfault in 2 out of 3 of my NetBSD 
5.0.2 boot attempts. Does anyone have an idea what could be causing 
this? Other OSs don't seem to be affected.
