Re: gcc problems on stalder
So I'm still seeing this issue. I see it on both stalder and
sompek. As far as I know they're both T2000's. I never see
those issues on the other buildds which I think are all
UltraSparc IIIi.
Stadler moved to a 3.2 kernel in the mean time, and I'm still
seeing the same problem.
The problem gets worse depending on the number of cores I use, and
I'm basicly using only 1 of the 32 cores because otherwise I just
have too many problems.
