http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1632 Summary: Dom0 crash if PCI passthrough VM crash or destroy Product: Xen Version: unstable Platform: x86-64 OS/Version: Linux-2.6 Status: NEW Severity: major Priority: P2 Component: 2.6.18 dom0 AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: paraic.gallagher@xxxxxxxxx Xen version 3.4.2 Kernel 2.6.18-164 Hardware IBM x3550 M2 If a VM using pci passthrough crashes or is destroyed by running 'xm destroy' it can result in a Dom0 crash. Output of dmesg on Dom0 after running 'xm destroy' shows something like: ACPI: PCI interrupt for device 0000:10:00.1 disabled irq 22: nobody cared (try booting with the "irqpoll" option) Call Trace: <IRQ> [<ffffffff802b36e6>] __report_bad_irq+0x30/0x7d [<ffffffff802b391d>] note_interrupt+0x1ea/0x22b [<ffffffff802b2e15>] __do_IRQ+0xbd/0x103 [<ffffffff8029008e>] _local_bh_enable+0x61/0xc5 [<ffffffff8026df5e>] do_IRQ+0xe7/0xf5 [<ffffffff803af7d5>] evtchn_do_upcall+0x13b/0x1fb [<ffffffff802608d6>] do_hypervisor_callback+0x1e/0x2c <EOI> [<ffffffff802063aa>] hypercall_page+0x3aa/0x1000 [<ffffffff802063aa>] hypercall_page+0x3aa/0x1000 [<ffffffff8026f501>] raw_safe_halt+0x84/0xa8 [<ffffffff8026ca7c>] xen_idle+0x38/0x4a [<ffffffff8024b0c8>] cpu_idle+0x97/0xba [<ffffffff80646b05>] start_kernel+0x21f/0x224 [<ffffffff806461e5>] _sinittext+0x1e5/0x1eb handlers: [<ffffffff803e39be>] (usb_hcd_irq+0x0/0x55) [<ffffffff803e39be>] (usb_hcd_irq+0x0/0x55) [<ffffffff803e39be>] (usb_hcd_irq+0x0/0x55) Disabling IRQ #22 I've tried booting with irqpoll options but this doesn't help. The IRQ (normally IRQ 20 or IRQ 22 in testing) is used by another device such as the RAID controller or USB hub, so the box stops functioning correctly. USB device failure appears benign until you need to connect any USB device. If the RAID controller is disabled usually the box stops responding immediately. A reboot is required to resolve the issue. This occurs on the IBM x3550 M2 (S8800) with both the Intel and Broadcom cards acting as the passthrough device. If the guest is stopped using the 'xm shutdown' command no problems seem to occur. -- Configure bugmail: http://bugzilla.xensource.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. _______________________________________________ Xen-bugs mailing list Xen-bugs@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-bugs
