It's not obvious what 'resource' it can't find when trying to use the card, but I *suspect* it's the interrupt. > Nov 11 20:40:31 mouse /kernel: ep0: utp/bnc[*UTP*] address 00:60:97:8e:e3:ff Slot 0 worked fine (though we don't know what resources it's using.) > <get rid of nokia card> > Nov 11 20:41:46 mouse /kernel: Card removed, slot 1 > Nov 11 20:41:46 mouse /kernel: Slot 1, unfielded interrupt (11) > Nov 11 20:41:46 mouse /kernel: Slot 1, unfielded interrupt (11) > <insert another modem card> > Nov 11 20:42:02 mouse /kernel: Card inserted, slot 1 > Nov 11 20:42:08 mouse pccardd[41]: No free configuration for card Intelligent Hmm, at this point it *appears* that the driver was allocated, but never de-allocated after failure. Let me look into that..... Looks good to me. > <set machdep.pccard.pcic_resume_reset to 1> This needs to be done at boot time (or at least before the first suspend) for it to have any effect. > <remove new modem card and reinsert the old one; push suspend> > Nov 11 20:45:34 mouse /kernel: Card removed, slot 1 > Nov 11 20:45:45 mouse /kernel: Card inserted, slot 1 > Nov 11 20:45:48 mouse /kernel: ep0: unload > Nov 11 20:45:48 mouse /kernel: Return IRQ=10 > Nov 11 20:45:48 mouse /kernel: stray irq 10 > Nov 11 20:45:48 mouse /kernel: Card disabled, slot 0 > Nov 11 20:45:48 mouse /kernel: Card disabled, slot 1 Fine, no cards to disable at slot 0 since the 'inserted' message never got around to the pccardd daemon long enough for it to have allocated a driver for the slot. > <suspended; press resume again> > Nov 11 20:45:53 mouse /kernel: resumed from suspended mode (slept 00:00:07) > Nov 11 20:45:54 mouse /kernel: Card inserted, slot 1 > Nov 11 20:45:54 mouse /kernel: Card inserted, slot 0 > Nov 11 20:46:01 mouse /kernel: sio1: probe test 3 failed > Nov 11 20:46:01 mouse pccardd[41]: driver allocation failed for Nokia Mobile Pho > nes > <note that now the network card is ignored!? Let's remove and reinsert it> I know why this happens. Basically, I need to *FORCE* the system to think the card was removed at suspend time, and *FORCE* it to think the card was inserted at resume time. Right now I 'fake' it. Basically, this is a 'known' bug that I haven't gotten time to fix. It shouldn't happen very often in any case. > Nov 11 20:46:36 mouse /kernel: Card removed, slot 0 > Nov 11 20:46:38 mouse /kernel: Card inserted, slot 0 > <bingo, we have network again> > Nov 11 20:46:49 mouse /kernel: ep0: utp/bnc[*UTP*] address 00:60:97:8e:e3:ff Yep, that's not a good solution, but it no longer locks up your machine like suspend/resume used to do. :) :) :) [ Well, in your particular case we still have sio lockups, but that's another story. ] Nate
