Since distro kernels contain some extra patches, may miss a significant
number of fixes, or even rely on different driver sources, you really
need to report this issue to your distro, who will ask for your exact
kernel version. It may be that this issue also affects the vanilla
kernel in the end, but in this case it will be reported by the distro's
maintainers once they've verified that it's not related to their kernel's
differences.

Hoping this helps,
Willy
