This message provides additional information regarding file system corruption I observed on the most recent Hurd builds.
I now believe that the corruption is due to a problem with the Hurd package itself, and not gnumach or hardware. I have replace the disk drive in question, verified all system BIOS settings, and deactivated UDMA and similar features that may not have proper support under GNUMACH or the Hurd. During high system load (such as during a compile) I get multiple INODE errors of the form: "ext2fs: Warning: bad directory entry: XX inode: YY offset: ZZ" I wiped all partitions clean on my system, then installed Marcus's earlier Hurd tarball gnu-19990505.tar.gz and the problems went away. I was able to run multiple compiles of a current CVS pull for GNU Mach without introducing errors to the filesystem. I then updated to the hurd-19990923 packages and attempted to recompile GNU Mach. The first recompile resulted in multiple INODE errors as seen previously. I do not know which part of the Hurd package is causing this problem, but I believe I have ruled out all other variables. Thanks, -Brent
