3.11.10.4 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Richard Weinberger <richard@xxxxxx> commit a926592f5e4e900f3fa903298c4619a131e60963 upstream. rhine_reset_task() misses to disable the tx scheduler upon reset, this can lead to a crash if work is still scheduled while we're resetting the tx queue.
