Category: None Group: None Status: Open Resolution: None Priority: 3 Private: No Submitted By: Carlo Marcelo Arenas Belon (carenas) Assigned to: Nobody/Anonymous (nobody) Summary: OpenSolaris 64bit panic with kvm-54 Initial Comment: Wouldn't mark it as a regression per-se as vanilla kvm-53 wouldn't work (because of the need for IDE patches to get it to run/install), but vanilla kvm-54 or kvm-54 + the same patches added to kvm-53 and including pre-kvm-55 patches like 71be592a14aa8d127315b2c47bf83cc0d810a341 wouldn't work. The panic is observed in kvm-54 (--no-kvm runs ok, and --no-kvm-irqchip doesn't help) while running nexenta OpenSolaris alpha 7 or beta 1 (other OpenSolaris distributions most likely affected as well) and with the following trace : panic[cpu0]/thread=fffffffec2de2260: BAD TRAP: type=e (#pf Page fault) rp=ffffff0001735f30 addr=0 occurred in module "unix" due to a NULL pointer dereference dbus: #pf Page fault Bad kernel fault at addr=0x0 pid=278, pc=0xfffffffffb83c189, sp=0xffffff0001736028, eflags=0x10246 cr0: 80050033<pg,wp,ne,et,mp,pe> cr4: 6b8<xmme,fxsr,pge,pae,pse,de> cr2: 0 cr3: 7dc4000 cr8: 0 rdi: 0 rsi: fffffffec0025630 rdx: fffffffec2de2260 rcx: 10000 r8: fffffffec0025630 r9: 3 rax: 0 rbx: 0 rbp: ffffff0001736080 r10: 1 r11: fffffffec1ad31e0 r12: 0 r13: fffffffec0025680 r14: c002548800000000 r15: 0 fsb: 0 gsb: fffffffffbc26ef0 ds: 4b es: 4b fs: 0 gs: 1c3 trp: e err: 0 rip: fffffffffb83c189 cs: 30 rfl: 10246 rsp: ffffff0001736028 ss: 38 ffffff0001735e10 unix:die+c8 () ffffff0001735f20 unix:trap+135b () ffffff0001735f30 unix:cmntrap+e9 () ffffff0001736080 unix:mutex_exit+9 () ffffff00017360c0 genunix:kmem_alloc+88 () ffffff0001736110 zfs:zio_push_transform+3a () ffffff0001736190 zfs:zio_create+256 () ffffff0001736240 zfs:zio_vdev_child_io+97 () ffffff0001736320 zfs:vdev_cache_read+182 () ffffff0001736370 zfs:vdev_disk_io_start+41 () ffffff0001736390 zfs:vdev_io_start+1d () ffffff00017363d0 zfs:zio_vdev_io_start+123 () ffffff00017363f0 zfs:zio_next_stage_async+bb () ffffff0001736410 zfs:zio_nowait+11 () ffffff0001736450 zfs:vdev_mirror_io_start+18f () ffffff0001736490 zfs:zio_vdev_io_start+131 () ffffff00017364b0 zfs:zio_next_stage+b3 () ffffff00017364e0 zfs:zio_ready+10e () ffffff0001736500 zfs:zio_next_stage+b3 () ffffff0001736550 zfs:zio_wait_for_children+5d () ffffff0001736570 zfs:zio_wait_children_ready+20 () ffffff0001736590 zfs:zio_next_stage_async+bb () ffffff00017365b0 zfs:zio_nowait+11 () ffffff0001736660 zfs:arc_read+4e8 () ffffff0001736700 zfs:dbuf_read_impl+129 () ffffff0001736760 zfs:dbuf_read+c5 () ffffff0001736810 zfs:dmu_buf_hold_array_by_dnode+1c4 () ffffff00017368a0 zfs:dmu_buf_hold_array+74 () ffffff0001736930 zfs:dmu_read_uio+4d () ffffff00017369c0 zfs:zfs_read+15e () ffffff0001736a30 genunix:fop_read+69 () ffffff0001736af0 genunix:vn_rdwr+161 () ffffff0001736c70 genunix:gexec+11c () ffffff0001736e90 genunix:exec_common+41d () ffffff0001736ec0 genunix:exece+1b () ffffff0001736f10 unix:brand_sys_sysenter+1f2 () while running in a Gentoo Linux 2007.0 host with Intel(R) Core(TM)2 CPU 6320. 32bit OpenSolaris works fine ---------------------------------------------------------------------- Comment By: Stefan Neufeind (neufeind) Date: 2010-06-18 17:13 Message: saw this with OpenSolaris 2009.6 (booting from iso, freely available) under a fully updated Fedora 13 (qemu-kvm-0.12.3-8.fc13.x86_64). using a 32bit-CPU for the guest works fine. ---------------------------------------------------------------------- Comment By: Jes Sorensen (jessorensen) Date: 2010-06-11 10:13 Message: Hi, I notice this one has been open for a long time. If you are still interested in this, could you please try it against a recent KVM. If that works fine, lets close this bug. Thanks, Jes ---------------------------------------------------------------------- Comment By: Carlo Marcelo Arenas Belon (carenas) Date: 2007-12-01 13:25 Message: Logged In: YES user_id=36771 Originator: YES kvm-53 also crashes randomly so it might not be a regression anyway, but though it might be interesting to mention that kvm-54 + previously detailed patches and also including fixes for is_long_mode as reported here : http://www.mail-archive.com/kvm-devel%40lists.sourceforge.net/msg08947.html are able to run most versions of Solaris 10 64bit x86 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1841658&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
