For the recent crashes the pointer seemed always consistent with previous mappings. Wondering whether the mapping might be invalidated by the hypervisor side. For additional information, when I start the domU, grant table debug shows the following at the beginning:
(XEN) grant-table for remote domain: 1 (v1) (XEN) [ 0] 0 0x212992 0x00000002 0 0x212992 0x19 (XEN) [ 1] 0 0x212991 0x00000002 0 0x212991 0x19 (XEN) [ 8] 0 0x1d26b7 0x00000001 0 0x1d26b7 0x19 when xenstored crashes, the middle entry goes away. But its impossible to say whether it goes away before the crash or just as a result of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1538049 Title: xenstore crashes with SIGBUS in domain_can_read() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xen/+bug/1538049/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
