Further limits: HZ<=1000 and bogomips<=3355 */ extern void __bad_udelay(void); Can you check why your driver is calling udelay() with a value > 2000? -- Martin Michlmayr http://www.cyrius.com/ -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
