We can confirm that we were able to trigger the issue on the latest 5.19 (commit: 3d7cb6b04c3f3115719235cc6866b10326de34cd) with the C-repro within a VM. We use this: https://syzkaller.appspot.com/text?tag=KernelConfig&x=cd73026ceaed1402 config to build the kernel. The issue triggers after around 143 seconds. For all the five times we tried, we were able to reproduce the issue deterministically every time. Please let us know if you need any other information. -- Thanks and Regards, Dipanjan
