Hi Mateusz

We used a rhel only patch to fix this problem. Now upstream patch 45b478951b2ba5aea70b2850c49c1aa83aedd0d2 should fix this problem. But there is a bug report against this patch https://lkml.iu.edu/hypermail/linux/kernel/2312.0/08634.html. So we didn't backport this patch to rhel and we still use the rhel only patch. We'll consider to backport in next release. For other OSes, you can have a try with this patch.

Regards
Xiao


Hello,
thanks for the info, I missed that this patch was merged with upstream.

Do we still get reports from systems with this fix?

Thanks,

We tested this with much older inbox kernels. I will try upstream kernel to verify this.Thanks, Mateusz
