Thanks, I will try to fix it ASAP. I got some problem with data integrity of my computer. It is not LinuxBIOS fault it seems - it happens with award too ;) I think my harddrive produces 1bit changes to the data sometimes. Effectively making mess in / FS. I have my data on RAID5 (except /) and those are 100% ok, so perhaps this looks like a problem of one particular device in the system.
I checked with debsums -c and I got random errors (checksum failure) on fixed set of files. This leads me to conclusion that it is not a memory or some other problem, but limited to the HDD. I will try to move root fs to other disk and I will check if it will be OK.
Thanks so far for the review,
Rudolf
