BTW, I should mention that, with a TMCLK of 33000 (very common, because it's just the PCI bus clock), increasing the limit from 300000 to 1000000 us actually increases the “counter” value by exactly 1 (from 11 to 12). This is probably why the older controller-specific hack of simply incrementing the counter worked. -- 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/
