Please think hard before including complete backtraces in upstream reports, they are very large and contain almost no useful information relative to their size so often obscure the relevant content in your message. If part of the backtrace is usefully illustrative (it often is for search engines if nothing else) then it's usually better to pull out the relevant sections.

Please split the core changes you are adding from the driver changes that use them.
The change does look reasonable for the issue, it's not ideal but I'm not sure it's avoidable with DPCM.
