I get this on only one of my machines but it's probably not that stange as they really don't have much in common other than being i386 compatible. Could old errors on the filesystem produce this error?? I have only run fsck under t8p6. The last one is incomplete but the kernel had inserted part of another file in the log so that was all I could get out. I have not noticed when this happens, If I find a pattern I post it later but It only functions as a nfs server and NAT box(ppp/netfiler/squid/...) so I don't think I could find much.
