file system corruption on x86 usb stick ext2

[normunds]

running openwrt on x86 usb pen stick. the sda2 partition gets corrupte d for no reasons. lots of inode errors and the file system always shows unclean no matter there is clean boot. Changed the owrt (backfire) version but problem was always there. changed the pendrive but no problem resolved. Tried squashfs but it wont boot. No way to clean the root partition.

This is the putty log showing the problem:

Please test Barrier Breaker or trunk.

I tried to test latest snapshot, but it didn't have a web interface.

Barrier Breaker r42625:
I followed the same commands as above and similar errors showed up.

Also, is it normal for jffs to show this in log?
