Hello Jan,
I'm observing this bug every day I resume my pc from hibernation,
then running some big network transfer ; I notice that because, using
SSH as network transport, it detects any data corruption.
Once the SSH transfert failed, the subsequent ones works … until next
hibernation / resume cycle ! I'm not sure whether it appears on a normal boot.
Fred.
