I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper)
could not write bytes: Broken pipe
speach dicpatcher disabled: edit etc/default/speach-dispatcher
saned disabled: edit ....
BUG: unable to handle kernel NULL pointer dereference at 0000009c
I've run Memory test in GRUB, everything is fine.
First time it occured when I was using rsync, second time when I was trying to install texlive.
Should I install whole system once again? Or can it be hardware problem? Or something else?
If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful.
