[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Oops in zap_pmd_range
I got the following on the April 1st nightly source release of the unstable tree. 2 CPU machine, SMP not configured, default configs for dom0 (256MB) and dom1 (512MB). Idle system for the most part, and I wasn't at the machine, came back to find this scrolling of my screen and in /var/log messages. Dom1 was hosed. Had to reboot subsequently. Ran some tests (netperf) between dom0 and dom1 to see if I could reproduce it, but haven't. I've since upgraded to 4/12/05 nightly snapshot. Haven't seen it again yet. Does this look like a valid kernel/oops? Any info that I could dig up?Apr 12 15:29:48 nivdom1 kernel: Unable to handle kernel paging request at virtua l address c6ec35e4 Apr 12 15:29:48 nivdom1 kernel: printing eip: Apr 12 15:29:48 nivdom1 kernel: c01434f6 Apr 12 15:29:48 nivdom1 kernel: *pde = ma 7ff64067 pa 00019067 Apr 12 15:29:48 nivdom1 kernel: *pte = ma 079aa063 pa 06ec3063 Apr 12 15:29:48 nivdom1 kernel: [<c0143718>] zap_pmd_range+0x57/0x75 Apr 12 15:29:48 nivdom1 kernel: [<c0143770>] zap_pud_range+0x3a/0x5e Apr 12 15:29:48 nivdom1 kernel: [<c0143808>] unmap_page_range+0x74/0x8b Apr 12 15:29:48 nivdom1 kernel: [<c014391c>] unmap_vmas+0xfd/0x223 Apr 12 15:29:48 nivdom1 kernel: [<c01489b7>] exit_mmap+0x84/0x156 Apr 12 15:29:48 nivdom1 kernel: [<c01158ee>] mmput+0x2b/0x94 Apr 12 15:29:48 nivdom1 kernel: [<c015e899>] exec_mmap+0xcb/0x12b Apr 12 15:29:48 nivdom1 kernel: [<c015eaae>] flush_old_exec+0x123/0x9ca Apr 12 15:29:48 nivdom1 kernel: [<c015436b>] vfs_read+0xb9/0x129 Apr 12 15:29:48 nivdom1 kernel: [<c015e7c5>] kernel_read+0x4a/0x53 Apr 12 15:29:48 nivdom1 kernel: [<c017c627>] load_elf_binary+0x37d/0xc9a Apr 12 15:29:48 nivdom1 kernel: [<c013910e>] buffered_rmqueue+0x153/0x2ba Apr 12 15:29:48 nivdom1 kernel: [<c02016e9>] copy_from_user+0x3d/0x64 Apr 12 15:29:48 nivdom1 kernel: [<c017c2aa>] load_elf_binary+0x0/0xc9aApr 12 15:29:48 nivdom1 kernel: [<c015f5ee>] search_binary_handler+0xbb/0x2e9 thanks, Nivedita _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
