Hunter, I've seen the same warning in logs for computers running kernel 6.1= and 6.2 before and after these patches were applied. Also, it appears that the= re's already a bug report put together for this warning (see bug w/ id 202541). Also, since I'm writing a quick comment, I'll give an update on testing the kernel with these patches applied. I haven't had any problems so far on any computer running kernel 5.15, 6.1 or 6.2 with these patches applied over the past 6 days, and the number of TRBs has remained at 512 on all 5 computers.= =20 I'm becoming more and more certain as they days go by that these patches fix this bug, and I'm okay with running a patched kernel for the time being. --=20 You may reply to this email to add a comment.
