Still the observations are sort of interesting (just for the record): 1) The problem is due to interrupt sharing. The IRQ is shared between yenta and 3c59x. 2) Without the yenta driver the box resumes. 3) Without the 3c59x driver the box resumes. 4) If yenta is woken up _before_ 3c59x, the box resumes. 5) If yenta is woken up _after_ 3c59x, the box hangs. Unfortunately, this is the default, because of the PCI device numbers. > And I admit, it is his turn to resume this month.
