E.g. "sync" is guaranteed to hang, but other tasks too. This seems to be mainly the case on "sd" disks (both sata and USB) where as my main nvme drive seems fine, which has probably saved me from worse issues... Here are 4 task stuck reports from my last boot, where I had to turn off the machine by keeping the power button pressed for 4 seconds.
