I tried that with 2.6.17-rc3, but it doesn't seem to have any effect.

I'm not sure if this has any effect on the sdhci issue, but during a normal suspend&resume (i.e. when sdhci has been rmmoded earlier) I get the following error about the PCMCIA CardBus slot, which is on the same PCI channel as the card reader (01:03.0 and 01:03.2 respectively): May 4 09:37:38 leevi PCMCIA: socket c14d8828: *** DANGER *** unable to remove socket power And the PCMCIA slot doesn't work either after a suspend&resume. I haven't tested FireWire yet (which is also on the same PCI channel 01:03.1), but I will shortly. -- Jani-Matti Hätinen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
