[Xen-ia64-devel] crash while unpacking tar.bz/tar.gz archives

[Jan Werner <jan.werner@xxxxxxxx>]

hi

i've been running several domU's on my tiger4 system in the last week 
under heavy load, well everything worked fine, as long as i have not 
been unpacking tar files.
the whole machine crashes if i try to extract tar / tar.bz2 or tar.gz 
files, well seems that not every single try crashed the whole machine
happens if i do that in dom0 as well as domU

i'm getting following output on the console:
