I'm not sure that lengthening the timeout is going to help - with the older IDE drivers, I've never had the laptop wait on disk IO for longer than about 5 seconds even when the disk has been spun down. Is this timeout parameter is only changeable by rebuilding the kernel? -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
