hi remember this bug?
http://bugs.archlinux.org/index.php?do=details&id=873
it was not a konsole bug but
first i blamed it on my hardware but
after running memchecks, power supply change, bios update/settings etc.

i found the reason for this problem is:

gzip

if you try to compress a directory whith 18000 files at the end it is 300 MB by using:
tar xvfz xy.tar.gz
it definitly happens quite often that i got a complete system freeze, not always but thats really annoying!. wonder nobody else has this problem
happens too with building large packages like the kernel flightgear-data, openoffice

now i updated to gzip 1.3.3 and this problems are gone
here is the PKGBUILD:
