I tried passing mem=2048m to the kernel. This is with 2.6.16.13. This did fix the USB ehci problem. Of course the kernel only sees half of my RAM, so this is not a satisfactory long-term workaround. As for your other suggestions, I'm not sure how to implement those. I'm not a kernel developer. If you can give me more specific instructions or send me a patch I would be happy to try those out. Otherwise, if you feel that this is unrelated to the other entries in bugzilla with similar symptoms, I would be happy to submit a bug report. - 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/
