Comment 3 for bug 672793

More information. Another lockup. Can ping host. Can not ssh in. This time Ctl-Alt-F1 gave me a console. Could not login but there was a ext4_fine_entry error.

Also this is system is configured with / on an ADATA SSD S599 64GB disk. It is possible these problems started occurring after an update but also could be related to the EXT4 file system on a SSD. I see a somewhat related bug 453579 about ext4. IN addition I see there is some ext4 patches in 2.6.37-rc1called "ext4: Add batched discard support for ext4".
