gcc problems on stalder
I've had a few packages fail to build on the new buildd stalder.
2 example logs are icewaesel:
It includes messages like: "The bug is not reproducible, so it is
likely a hardware or OS problem."
It has always build fine on the other buildds, so I'm assuming
that as gcc tells me, it's a hardware or OS problem.
Those builds where first with -j32, then with -j8, that is
setting DEB_BUILD_OPTIONS to parallel=32.
All other sparc buildds run with parallel=2 and I've never seen
them having a problem. All others also only have 2 CPUs.
stadler has this in /proc/cpuinfo:
cpu : UltraSparc T1 (Niagara)
fpu : UltraSparc T1 integrated FPU
pmu : niagara
prom : OBP 4.30.3 2009/06/08 13:29
type : sun4v
ncpus probed : 32
ncpus active : 32
So my question is, is this some known problem, like for instance a
kernel problem that randomly does something wrong that's triggered
by having many proceses using much cpu time?
Or maybe a hardware problem, for instance I'm heating things up
using so many processes?
Or something else?
PS: Please CC me, I'm not on the list.
