Something seems to currently be quite broken in HEAD for PowerPC, at least on the AIM platform. I'm getting almost immediate panics all over the place in the kernel, usually indicating memory corruption somehow (faults on bogus addresses, illegal instructions, etc...). This is a heads-up to those thinking of updating systems or who might know what happened. The change is on order a week old, and I believe newer than the 20th. I have not done a full binary search yet, but it is not related to the following (checked by selective reversion of bits of the tree, or disabling bits): - USB code - ATA code - Anything in sys/powerpc (the Altivec import in particular) - Any changes to kernel compile flags or the contents of /usr/src/share/mk The panics seem to correlated with file system use (either UFS or NFS), but that may just be testing more code paths than a pure computational load. -Nathan
