--- Comment #39 from Stanislav Brabec 2008-05-12 13:35:35 MST ---
I was not able to reproduce the problem with an arbitrary flash, but when I
restored the original image back, the I got the corruption again.
Steps to reproduce: see comment 37
ls -al /mnt/
ls: cannot access /mnt/testdir: Input/output error
total 8
drwxrwxr-x 3 root users 4096 Jan 1 1970 .
drwxr-xr-x 25 root root 4096 May 12 20:58 ..
d????????? ? ? ? ? ? testdir
Note that writing large amount of data to this flash works. Only last few
blocks are lost.
