Hello Xen developers! I finally managed to get my first real box for Xen -- and now I'm in trouble ;-) run Xen-3.0 on an Dual-Opteron Dual-Core box with SUSE 10.0 kernel/xen RPMs from current yast online update packages I get the following system crash quite easy within a few minutes (~1-5 min) with only dom0 and running ~4-5 processes with just a cpu loop ("while (1) ;") here is the most complete information I got from syslog so far: kernel: ----------- [cut here ] --------- [please bite here ] --------- kernel: Kernel BUG at "arch/xen/x86_64/mm/hypervisor.c":198 kernel: invalid operand: 0000 [1] kernel: CPU 0 kernel: Modules linked in: bridge ipv6 button battery ac af_packet tg3 ohci_hcd usbcore i2c_amd8111 i2c_amd756 i2c_core hw_random generic parport_pc lp parport ext3 jbd dm_mod reiserfs fan thermal processor sg ide_cd cdrom aic79xx scsi_transport_spi amd74xx sd_mod scsi_mod ide_disk ide_core kernel: Pid: 7082, comm: mybuffer Not tainted 2.6.13-15-xen kernel: RIP: e030:[<ffffffff8011f987>] <ffffffff8011f987>{xen_pgd_pin+71} kernel: RSP: e02b:ffff88000f9b7b28 EFLAGS: 00010282 kernel: RAX: 00000000ffffffea RBX: ffff88001f08a040 RCX: ffffffff8011f983 kernel: RDX: 0000000000000000 RSI: 0000000000000001 RDI: ffff88000f9b7b28 kernel: RBP: ffff88000f9b7c08 R08: 0000000000000003 R09: 0000000000000000 kernel: R10: 0000000000007ff0 R11: 0000000000000246 R12: ffff88001d3d0e80 kernel: R13: ffff8800016d77f0 R14: 000000ae03419fd2 R15: ffff88001a2eb8f8 kernel: FS: 00002aaaac4001a0(0000) GS:ffffffff804bbe80(0000) knlGS:00000000556ac6c0 kernel: CS: e033 DS: 0000 ES: 0000 kernel: Process mybuffer (pid: 7082, threadinfo ffff88000f9b6000, task ffff88001a2eb6e0) kernel: Stack: ffff880000000003 00000000000b5eb6 ffff8800016d77f0 000000ae03419fd2 kernel: ffff88001a2eb8f8 ffffffff8011ea75 ffff88001f08a040 ffffffff80348ddd kernel: 00000000000010da ffff88001a2eb6e0 kernel: Call Trace:<ffffffff8011ea75>{mm_pin+325} <ffffffff80348ddd>{schedule+1261} kernel: <ffffffff801572e0>{sync_page+0} <ffffffff803490af>{io_schedule+15} kernel: <ffffffff8015731b>{sync_page+59} <ffffffff80349bb1>{__wait_on_bit_lock+65} kernel: <ffffffff8015740f>{__lock_page+95} <ffffffff801488c0>{wake_bit_function+0} kernel: <ffffffff80157685>{find_get_page+21} <ffffffff80158f5f>{do_generic_mapping_read+479} kernel: <ffffffff80157860>{file_read_actor+0} <ffffffff80159a90>{__generic_file_aio_read+384} kernel: <ffffffff80159c8b>{generic_file_read+187} <ffffffff80156184>{__do_IRQ+244} kernel: <ffffffff80115369>{do_IRQ+57} <ffffffff8010de16>{evtchn_do_upcall+118} kernel: <ffffffff80148760>{autoremove_wake_function+0} <ffffffff8017ace5>{vfs_read+229} kernel: <ffffffff8017b4c3>{sys_read+83} <ffffffff8012101b>{ia32_sysret+0} kernel: <ffffffff80120fa8>{ia32_syscall+0} kernel: kernel: Code: 0f 0b a3 58 81 36 80 ff ff ff ff c2 c6 00 48 83 c4 28 c3 66 kernel: RIP <ffffffff8011f987>{xen_pgd_pin+71} RSP <ffff88000f9b7b28> unfortuneately I didn't yet manage to get the _full_ crash info for both the hypervisor _and_ the dom0 kernel in syslog, and I'm still wrestling with the serial console when using xen. right now I only have a "real" screen shot (4 Mpixel;) which shows both information, if this is needed... system setup: dual-cpu dual-core AMD Opteron 8 GB ram SUSE 10.0 x86_64 + online update running 32bit SUSE 10.0 xen-3.0 doesn't show this crash, only the x86_64 system. which other information do you need ? thanks for any pointer & help, Harald Koenig -- "I hope to die ___ _____ before I *have* to use Microsoft Word.", 0--,| /OOOOOOO\ Donald E.
