I seem to hit it with heavy disk & cpu IO is in progress on this PowerBook G4. Full dmesg & .config: http://nerdbynature.de/bits/3.2.0-rc1/oops/ I've enabled some debug options and now it really points to slub.c:2166 http://nerdbynature.de/bits/3.2.0-rc1/oops/oops4m.jpg With debug options enabled I'm currently in the xmon debugger, not sure what to make of it yet, I'll try to get something useful out of it :) Christian. -- BOFH excuse #399: We are a 100% Microsoft Shop. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
