I did fix one major SMP bug in the pcmcia-cs drivers just a couple days ago; the beta at http://pcmcia-cs.sourceforge.net/ftp/NEW has the fix. I'm not sure if it is really the same bug you describe, though, since no one else has reported the ds module causing an immediate oops. The standalone drivers are unlikely to help, though, because the orinoco_cs driver in the standalone package is virtually identical to the one in the current 2.4.* kernel. Actually, though, you could try the (older) wvlan_cs driver in the pcmcia-cs package. You can do that with your current kernel drivers, even. Unpack the pcmcia-cs package, do "make config", then cd to the wireless subdirectory and do a "make" there. That should build a wvlan_cs module that will mesh with your kernel PCMCIA subsystem. It will at least give you another data point. I don't know how to interpret your oops report; you should probably also forward the bug to David Gibson, hermes@gibson.dropbear.id.au, since he is the orinoco maintainer. -- Dave - 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/
