Got this Oops while diffing the 2.3.27pre5 tree against a 2.3.27pre6 tree to see what changed. I started the diff redirected out to a file and switched to X to browse the web and do some stuff while I was waiting. When in X, I moved to another desktop and loaded an rxvt. I noticed something said "Segmentation fault" in my .cshrc, so I loaded another to see if it happened again -- same thing. I said "hmm", and switched back to Netscape, at which point Netscape didn't repaint and I couldn't do anything more.
I got the Oops from my other box connected via serial cable:

This is on my normal SMP development box that was previously showing the "bit already cleared" errors that I reported twice before with 2.3.25. I fsck -f'd everything immediately before booting with 2.3.27pre5 to make sure nothing was corrupted before booting this kernel.
See linux-kernel messages with subject "2.3.25 filesystem corruption" for more details about my hardware.
