I've now upgraded the Dom0 kernel from 2.6.27.9 to 2.6.27.10 (factory) - and again run into problems with the delegation of PCI HW (motherboard USB controller): With a 2.6.27.10 Dom0 kernel from factory the patched 2.6.27.10 DomU starts up ok and has access to the PCI hardware, albeit with slightly different behaviour: Where only IRQ23 was visibly used in DomU before, IRQ18 now is visibly used, too (although it is shared with the Dom0 eth2 device). When the DomU is shutdown, cleanup of the shared interrupt does not seem to work - the DomU loops in the final phase of the shutdown and the Dom0 produces a stack trace. This behaviour has only been observed on the second "power-cycle" for the DomU (at least up to now). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
