Comment 19 for bug 210468

I'm seeing this too, and something about it is causing my system to hang. Basically, when I come in the morning I can't do hardly anything, including reboot. Investigation has shown that it's because any attempt to read the /proc/mounts file causes a permanent hang on the process (can't even kill -9 etc.). Lots and lots of programs, even ones like "ls", try to read this file. I have to power-cycle the system to recover. My system load is above 7, even though my CPU usage is negligible (a sure sign that processes are hung in the kernel).

Last night I started a script that ran date, then cat /proc/mounts, then sleep 15 and left it running all night. I got the hang at 22:51 and looking through my logs, sure enough right at that exact time I saw a slew of these .Trash access errors show up in my /var/log/syslog file. I'm going to continue to test this theory to see if it was just coincidence or not.
