[Bug 1103426] New: Tumbleweed installation freezes when using QXL driver
http://bugzilla.opensuse.org/show_bug.cgi?id=1103426 Bug ID: 1103426 Summary: Tumbleweed installation freezes when using QXL driver Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Virtualization:Tools Assignee: virt-bugs@suse.de Reporter: iforster@suse.com QA Contact: qa-bugs@suse.de CC: fabian@ritter-vogt.de, rbrown@suse.de Found By: --- Blocker: --- It happened several times to me that the installation of Tumbleweed just froze at various stages of the installation when using virt-manager together with the default QXL driver. Symptoms: The UI will just freeze completely. Switching to other terminals is not possible either. However when starting an SSH daemon it's still possible to connect to the machine. When doing so no relevant output can be seen in dmesg. When attaching to the Xorg process via strace nothing gets printed at all, getting the stack trace (which won't change) of X shows the following: 1:install:~ # cat /proc/`pidof Xorg`/task/*/stack [<0>] ttm_eu_reserve_buffers+0x1d9/0x2c0 [ttm] [<0>] qxl_release_reserve_list+0x53/0x130 [qxl] [<0>] qxl_cursor_atomic_update+0x17e/0x2a0 [qxl] [<0>] drm_atomic_helper_commit_planes+0xae/0x210 [drm_kms_helper] [<0>] drm_atomic_helper_commit_tail+0x26/0x60 [drm_kms_helper] [<0>] commit_tail+0x58/0x70 [drm_kms_helper] [<0>] drm_atomic_helper_commit+0x103/0x110 [drm_kms_helper] [<0>] drm_atomic_helper_update_plane+0xf0/0x110 [drm_kms_helper] [<0>] __setplane_internal+0x134/0x260 [drm] [<0>] drm_mode_cursor_universal+0xdf/0x1c0 [drm] [<0>] drm_mode_cursor_common+0x167/0x1d0 [drm] [<0>] drm_ioctl_kernel+0x5b/0xb0 [drm] [<0>] drm_ioctl+0x194/0x350 [drm] [<0>] do_vfs_ioctl+0x90/0x5d0 [<0>] ksys_ioctl+0x60/0x90 [<0>] __x64_sys_ioctl+0x16/0x20 [<0>] do_syscall_64+0x60/0x110 [<0>] entry_SYSCALL_64_after_hwframe+0x49/0xbe [<0>] 0xffffffffffffffff -- You are receiving this mail because: You are on the CC list for the bug.

but we would still need to solve this bug.
I agree with that. Since this problem only occurs intermittently, it is hard to test. I would like some guidance on what sort of information I should collect (and attach) when I next run into the problem. -- You are receiving this mail because: You are on the CC list for the bug.

Can you test with latest TW which runs 4.18.7-1.5 ?
The difficulty is that these freezes are intermittent, so they are hard to test. My most recent freeze was on Saturday or Sunday. I guess I should keep better records. However, I was running a 4.18 kernel at that time. Can you suggest what information I should collect when there is a freeze. Keep in mind that I am able to login with ssh and get a root command line. A little guidance on what to look for would be helpful here. -- You are receiving this mail because: You are on the CC list for the bug.
