EXT4 filesystem errors after switching to SSD drive
I have switched to Crucial M4 SSD drive this week and as soon as I booted the copied-over system from a new disk, I began noticing EXT4 errors in dmesg. They seem pretty serious and I am being warned that "data WILL BE lost". I can't confirm any data loss yet, but maybe just because I didn't notice it.
What's more, it seems that whenever I do something disk intensive, these errors tend to show up in dmesg and at the same time some processes segfault, like google-chrome's processes (plugins, tabs) or Virtualbox. It gives a feeling that maybe they are being starved by I/O scheduler. I tried noop and deadline and it's been the same, I went back now to CFQ to see if this changes anything.
