zfs-linux/unknown (armhf) Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1]. https://people.canonical.com/~ubuntu-archive/proposed- migration/bionic/update_excuses.html#linux-oracle-5.4 [1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions Thank you! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1877394 Title: Kernel panic due to NULL ringbuffer vaddr dereference in i915 Status in linux package in Ubuntu: Invalid Status in linux source package in Focal: Fix Released Bug description: SRU Justification: [Impact] A sauce fix for a kernel panic in i915 that I frequently experienced was fixed by upstream. [Fix] The sauce patch I made should be dropped in exchange for the proper upstream fix. [Test] I tested the upstream fix and can confirm it fixes the crashes I experienced. [Regression Potential] Low. The upstream fix for this bug is tiny and we get to remove a nasty sauce patch. --- This is what the crash looks like: BUG: unable to handle page fault for address: 0000000000003448 RIP: 0010:gen8_emit_flush_render+0x163/0x190 Call Trace: execlists_request_alloc+0x25/0x40 __i915_request_create+0x1f4/0x2c0 i915_request_create+0x71/0xc0 i915_gem_do_execbuffer+0xb98/0x1a80 ? preempt_count_add+0x68/0xa0 ? _raw_spin_lock+0x13/0x30 ? _raw_spin_unlock+0x16/0x30 i915_gem_execbuffer2_ioctl+0x1de/0x3c0 ? i915_gem_busy_ioctl+0x7f/0x1d0 ? i915_gem_execbuffer_ioctl+0x2d0/0x2d0 drm_ioctl_kernel+0xb2/0x100 drm_ioctl+0x209/0x360 ? i915_gem_execbuffer_ioctl+0x2d0/0x2d0 ksys_ioctl+0x87/0xc0 __x64_sys_ioctl+0x16/0x20 do_syscall_64+0x4e/0x150 entry_SYSCALL_64_after_hwframe+0x44/0xa9 This bug was fixed by "UBUNTU: SAUCE: drm/i915: Synchronize active and retire callbacks" but there is an upstream fix for it, "drm/i915/gt: Make intel_ring_unpin() safe for concurrent pint". Let's replace the sauce patch with the upstream fix.
