Only the first 0x48 registers are defined by the base specification; the rest are chip and/or manufacturer specific. The registers which Ico is changing are specific to the ENE CB1410, which are a clone of the TI chips. Your cardbus bridge isn't a clone of TI, so I wouldn't expect the same fix to work for you. However, we now have some of the clues, so... PS, in your first mail I have on this subject, you mentioned someone called "Timothy" who had the same problem, and was using Red Hat with a TI bridge. I don't seem to have any responses from him, and it would be good to get some feedback from him as well. Specifically whether stock 2.6.5 works or exhibits the same problem. Stock 2.6.5 with TI bridges should already set 0x81 to 0xd0, and they don't have the other register at 0xc9. This only leaves the cardbus bridge latency timer. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 PCMCIA - http://pcmcia.arm.linux.org.uk/ 2.6 Serial core - 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/
