Whatever the problem is, only seems to show up when ADMA is enabled, and so the patch that added ADMA support shows up as the culprit from your git bisect. However, from what Chr is reporting, 2.6.19 with the ADMA support added in doesn't seem to have the problem, so presumably something else that changed in the 2.6.20-rc series is triggering it. Doing a bisect while keeping the driver code itself the same will hopefully identify what that change is.. - 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/
