Subject: sdhci_pci: card insertion not detected after s2disk
Date: Sun, 24 Oct 2010 14:36:54 +0200 [thread overview]
Message-ID: <20101024123540.GA14424@nb-core2.darkstar.lan> (raw)
Hello,
I noticed that after resuming from s2disk the controller does not
detected when a card is inserted into the slot. The controller seems to
work fine after s2ram. I'm currently running kernel 2.6.36, this is the
hardware:

There are changes in the PCI configuration space after resume.
dmesg:

No errors that I can see. After rmmod sdhci_pci && modprobe sdhci_pci
the controller works fine again.
Should I try adding additional quirks?
