Something's very fishy there: [quote] Digging into suspend-utils code shows that the following ioctl fails on "/dev/snapshot": Code: ioctl(dev, _IO(3, 1), 0); [end quote] but that's _not_ anything freeze-related - that's HDIO_GETGEO, and with zero as last argument it will fail, no matter what. With EFAULT, if nothing else... Which ioctl() it really is? A bit further down you write "I modified suspend code to see errno, so freeze on /dev/snapshot fails [with EAGAIN]", so you have isolated the call in question. Could you quote the actual code? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
