This bug is awaiting verification that the linux- azure-5.15/5.15.0-1033.40~20.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The fio command does not consistently result in a kernel panic, but the test runs fio enough times to result in consistent kernel panic. The panic is most often observed on instances with many cores and disks. [Test Case] Using an instance with 96 cores and 16 disks: sudo fio --ioengine=libaio --bs=1024K --filename=/dev/sda:/dev/sdb:/dev/sdc:/dev/sdd:/dev/sde:/dev/sdf:/dev/sdg:/dev/sdh:/dev/sdi:/dev/sdj:/dev/sdk:/dev/sdl:/dev/sdm:/dev/sdn:/dev/sdo:/dev/sdp --readwrite=read --runtime=120 --iodepth=32 --numjob=96 --name=iteration23 --direct=1 --size=8192M --group_reporting --overwrite=1 Test results from Microsoft and myself are positive. No panics were observed. [Regression Potential] The fix is an upstream patch from 5.17, commit 0bd2fbee9d0b7f801a9c0264d90b1e0d8053f395 ('scsi: storvsc: Fix unsigned comparison to zero'). Regression potential is low.
