Yes (test with the same binary):
bash-2.05b# while /bin/true; do /bin/true; done
Kernel panic: Kernel mode fault at addr 0x1f, ip 0x400d1397
However, I discovered that an old 2.6.0 kernel works well. I think that had
2.6.0-test9 patch; so I think that this is related with the NET: Registered
... hang, which was solved with the same patch. That does not happen on
different compilation env.s, but I think that is random: a crazy pointer
failing in different places.
