| |
When resuming from suspend-to-RAM, the NMI watchdog detects a lockup in ide_wait_not_busy. Here's a screenshot of the trace taken by a digital camera: http://www.uamt.feec.vutbr.cz/rizeni/pom/DSC03510-2.JPG
Let's touch the NMI watchdog in ide_wait_not_busy. The system then resumes correctly from STR.
