this morning, when booting up my Lenovo T61 T7500 notebook from hibernation - damnit! - the bluescreen of death appeared saying "Driver Irql Not Less Or Equal", and the machine rebooted immediately.
Of course, all hibernation data was lost, which was pretty annoying.
My only concern is to resolve the cause of this irq conflict so that the problem and data loss will not occur again. The device manager does not indicate anything special, i.e., no exclamation marks.
The system is maintained with Lenovo System update.
What can I do to isolate the problem?
Helpful comments are greatly appreciated - thanks in advance.
