The problem with doing resets unconditionally in kernel is that if e.g. the user is using nextboot(8) and the kernel stuck at a later time, there is nothing that resets the system to recover it to a previously known good state, and that would defeat a good fraction of legitimate usage of watchdogs. -- You are receiving this mail because: You are the assignee for the bug.
