Hi, I have uploaded a new set of rebased openSUSE dom0 xen patches and Gentoo ebuild for 2.6.31 to http://code.google.com/p/gentoo-xen-kernel/downloads/list, Jan Beulich recently identified the cause of the null pointer crash and other stability problems that affected previous versions and with the necessary fixes applied the kernel has run for 2+ days with no issues at all, I think you will find

...ce (netfront implements when accelerator is enabled). That seems to make sense, e.g. blkfront shadows pending reqs, and requeue them after resume. However considering log dirty mode, there''s an assumption for this style: **There must be some CPU issued accesses to target data page before xen_suspend is invoked, if that page is serviced by BE driver and has been dequeued from FE queues within the loop copy process. Or else log dirty mode is not triggered to re-transimit that page in next loop. ** Does that assumption always hold true for existing FE drivers? Thanks, Kevin _________________...
