I have an issue with the driver. It always crashes my laptop if it wake from sleep with expresscard inserted and disk connected to it.

If I soft-eject express card before sleep with statusbar icon, all is fine. If I just unmount the drive but not the card, I always have a crash on wake.
If I disconnect the drive from USB port, but not the card (with soft-eject from status bar, it still active), there is no kernel panic: notebook wakes fine without any issue and express card is functional.

Tried -gux_nosleep kernel flag without success. Crash dump and xhcidump output in attachment. If you need more info from xhcidump just let me know.

I also updated ExpressCard with latest firmware for Renesas uPD720202 to 2.0.2.0 version under Windows. It didn't help.

The same behaviour under OS X 10.9 GM. I have kernel panic there too in this situation.

    Confirmed.
    NukeSlot calls DeallocRing on stream rings which are now shared.
    Will fix this and upload solution soon.
    For the time being, disconnect the drive before sleep.

    Please install 1.2.7d2 from Snapshots, try and see if it fixes this. I'm closing it. If it still KPs, reopen.
