Sounds exactly like the problem i was having. However the logical thought behind it was that it must be either 1) a hardware specific problem, or 2) a generic usb driver problem. Since only a handful of people seen the problem, then this logically leads one to the conclusion that our usb<->ide devices have some marginal timing issues that are being triggered with the new code. > And running my backup on USB 1.1 is not an option, way to slow. Well in my case i opted for the slow backup rather than the no backup if i wanted to move forward with the new kernels.

Well, I only see this with 2.4.22-pre/rc, so this is definitly not a hardware-problem, it runs just fine with 2.4.21 at 9950 kB/s. And running my backup on USB 1.1 is not an option, way to slow. -- Fridtjof Busse panic("Lucy in the sky...."); 2.2.16 /usr/src/linux/arch/sparc64/kernel/starfire.c - 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/
