Isolation for broken hardware during system suspend
summary
Drivers can abort system suspend by returning errors from their suspend callbacks, which leaves a laptop seemingly asleep while it actually is not; networking drivers failing resume and device resets that then fail are common examples. The talk frames the dilemma: either honor driver vetoes or provide a system-level override like the old S3 “big hammer.” No patch is presented; discussion points include detecting genuinely broken hardware and applying quirks to force suspend when safe.
