Regarding rsod, vtrm reinitialization is a permanent fix
if & only if the rsod issue is caused by a freak vtrm region corruption in Flash memory, but if ever the vtrm region corruption is caused by a defective NOR chip, rsod may keep coming back in which case a proper fix would imply replacing the nor chip on the main board.

Here are a few notes on rsod in the wiki.
