Howdy,
After I managed to get 3.9 successfully up and working on my Arndale system, I started to stress test KVM. I simply took a kernel tree and compiled it until it failed:
#!/bin/bash -e
while true; do
make clean
make -j4
done
This eventually happened after a few successful runs:
crypto/serpent_generic.c: In function ‘__serpent_decrypt’:
crypto/serpent_generic.c:560:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.opensuse.org/> for instructions.
make[1]: *** [crypto/serpent_generic.o] Error 1
make: *** [crypto] Error 2
make: *** Waiting for unfinished jobs....
Does anyone have an idea how to debug this? Will mentioned TLB breakage that he had a branch for, so I'm going to try his branch next as guest kernel.
Has anyone else seen this? It's very clearly reproducible.
Alex
