Hi Dong, I have been reading:
https://lore.kernel.org/kvm/CACGkMEs1t-ipP7TasHkKNKd=peVEES6Xdw1zSsJkb- [email protected]/T/#m167335bf7ab09b12fec3bdc5d46a30bc2e26cac7 and I tried to reproduce the problem with 23.10's userspace, but I can't see the same crash. By virtio legacy devices, you mean 0.97 virtio devices from ~2014 right? Would I need a 14.04 hypervisor to see this issue? I can try deploy one. In any case, I have started building the below commit into a test kernel for you to try. commit c8fae27d141a32a1624d0d0d5419d94252824498 From: Li Zhang <[email protected]> Date: Sat, 16 Mar 2024 13:25:54 +0800 Subject: virtio-pci: Check if is_avq is NULL Link: https://github.com/torvalds/linux/commit/c8fae27d141a32a1624d0d0d5419d94252824498 This kernel is going to take about 3 hours to compile, so wait 3 hours after this message before installing. You can also check status here: https://launchpad.net/~mruffell/+archive/ubuntu/lp2067862-test Please note this package is NOT SUPPORTED by Canonical, and is for TESTING PURPOSES ONLY. ONLY Install in a dedicated test environment. Instructions to Install (On a noble system): 1) sudo add-apt-repository ppa:mruffell/lp2067862-test 2) sudo apt update 3) sudo apt install linux-image-unsigned-6.8.0-31-generic linux-modules-6.8.0-31-generic linux-modules-extra-6.8.0-31-generic linux-headers-6.8.0-31-generic 4) sudo reboot 5) uname -rv Look for "6.8.0-31.31+TEST2067862v20240614b1". You might be asked to abort removing the currently running kernel. Say no. Does the test kernel fix your issue? Can you help me define the testcase so I can write a SRU template? How do you reproduce the problem?
