Since 5.4.206 is a longterm release kernel, we were under the impression that the community is still accepting fixes and patches for the same. I understand that adding another bug to the already pending queue of syzbot reported issues is not going to help the developers much. Therefore, we will definitely try our best to analyze the issue and provide a fix in the coming days. Can you please confirm that it is worth the effort for the longterm release kernels? > > thanks, > > greg k-h -- Thanks and Regards, Dipanjan
