Linux 3.18 no longer boots under Xen. This has been true for over half a year. The Xen project CI has been sending automatic mails including bisection reports (see below). I emailed Xen kernel folks and got no takers for fixing this. Unless this is fixed soon, or at least someone shows some inclination to investigate this regression, I intend to drop all testing of this "stable" branch. It has rotted and no-one is fixing it. > >> > *** Found and reproduced problem changeset *** > >> > > >> > Bug is in tree: linux > > git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git > >> > Bug introduced: 6b1ae527b1fdee86e81da0cb26ced75731c6c0fa > >> > Bug not present: ba6984fc0162f24a510ebc34e881b546b69c553b > >> > Last fail repro: http://logs.test-lab.xenproject.org/osstest/logs/136574/ > > > > It seems that there is something wrong with the IGB driver.
