I've been over that code a number of times, and have no idea how that bug could be triggering. :-) Alternately, if you find unstable too unstable (or if you don't want to find out), you can revert xen-4.1-testing c/s 22977:6af8e01d3e4a, which turns off the debugging code I'd put in for the 4.1 release. Any version works for me, since this is just for testing purposes (this isn't a production machine yet). On xen-unstable, I'm seeing that the domU just hangs after it starts. The stubdom chews CPU very slowly, but there is no activity on the main domain: dallas-dodec226-5 customers # xl listName ID Mem VCPUs State Time(s) Domain-0 0 1500 4 r----- 4061.2 testvds4 3 803 1 -b---- 0.0 testvds4-dm 4 32 1 -b---- 0.6 It's hanging after this: (XEN) irq.c:258: Dom3 PCI link 1 changed 0 -> 10 (XEN) HVM3: PCI-ISA link 1 routed to IRQ10 (XEN) irq.c:258: Dom3 PCI link 2 changed 0 -> 11 (XEN) HVM3: PCI-ISA link 2 routed to IRQ11 (XEN) irq.c:258: Dom3 PCI link 3 changed 0 -> 5 (XEN) HVM3: PCI-ISA link 3 routed to IRQ5 (XEN) HVM3: pci dev 01:2 INTD->IRQ5 (XEN) HVM3: pci dev 01:3 INTA->IRQ10 (XEN) HVM3: pci dev 03:0 INTA->IRQ5 (XEN) HVM3: pci dev 04:0 INTA->IRQ5 (XEN) HVM3: pci dev 02:0 bar 10 size 02000000: f0000008 (XEN) HVM3: pci dev 03:0 bar 14 size 01000000: f2000008 (XEN) HVM3: pci dev 04:0 bar 10 size 00020000: f3000000 (XEN) HVM3: pci dev 02:0 bar 14 size 00001000: f3020000 (XEN) HVM3: pci dev 03:0 bar 10 size 00000100: 0000c001 (XEN) HVM3: pci dev 04:0 bar 14 size 00000040: 0000c101 (XEN) HVM3: pci dev 01:2 bar 20 size 00000020: 0000c141 (XEN) HVM3: pci dev 01:1 bar 20 size 00000010: 0000c161 (XEN) HVM3: Multiprocessor initialisation:(XEN) HVM3: - CPU0 ... 40-bit phys ... fixed MTRRs ... var MTRRs [2/8] ... done.

Killing the domU works properly. I'll try 4.1-testing again with the patch reversion. -John _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
