Stability of 2.0_RCx?

Hi,

I don't know since when this happens, I haven't run NetBSD/dreamcast for
some months. 

Now I want to update to an up-to-date 2.0RC version, but I get strange
reboots or hangs.

Today the DC simply rebooted while it was unpacking a cross-compiled
base.tgz
(accessed over NFS).

Last week I tried to build perl-5.8 from pkgsrc, but the DC either
stopped and was unresponsive or it rebooted w/o notice.

It seems the DC port is quite broken currently, can I do something
to help getting it fixed?

rgards,
chris
