[Pkg-xen-devel] Bug#705124: base: Filesystem corruption issue

[Holger Levsen]

reassign 705124 xen
# even though i'm not 100% sure it's a xen issue, it smells like one,
# also because I use pretty similar setups (just without xen) without issues
#
# there are more logs from the bug submitter in the BTS
#
# and downgrading might also be approriate...
thanks
