@bgoncalv - we are assuming the latest rawhide kernel has this fix for the last few months. Is there an easy way to verify this works now? I assume a provision and maybe a few reboots while checking dmesg? Cheers, Don
We didn't have a reliable reproducer for it. Like only few times every a couple of months: https://datawarehouse.cki-project.org/issue/1601 But since February we haven't reproduced it any more. As we believe this is already fixed I'll close this as fixed in the current release. As I'll get notified as regression if we hit this issue again.
