Comment 18 for bug 528981

Thanks for your update, Stuart. In trying to save log files when the filesystem goes read-only, I've found it helpful to use either a USB key or SD Card, which can be mounted even when the boot filesystem has gone read-only. In most cases when testing for this problem, I even mount an SD Card as soon as my system boots so I can immediately capture the data when the (inevitable) corruption happens. You can then do something like "dmesg > /dev/sdc1/dmesg.txt" to capture data about the event, unmount the USB key, reboot and submit an update to this bug report.

You mentioned the RC; I'm guessing you're using kernel 2.6.32-21. We've been asked to also try using the "latest" upstream kernel. I've already tried the 2.6.33 series, which seems to solve the problem, but 2.6.34 is also available. Can you please help by getting an upstream kernel (either 2.6.33.3-lucid or 2.6.34-rc5-lucid) from here: http://kernel.ubuntu.com/~kernel-ppa/mainline . Full instructions and complete information about the process are at https://wiki.ubuntu.com/KernelMainlineBuilds .

You have my personal thanks for continuing to help on this problem, since this corruption problem is extremely frustrating!
