If I revert it, my system goes back to working correctly, but as is, it fails and wont allow my USB to work properly. I've tried adding a loop to poll this bit 10,000 times with a udelay(1) on each loop and it still fails, so it doesn't appear to be a timing issue. Is this check valid for all systems? -- Bluecherry: http://www.bluecherrydvr.com/ SwissDisk : http://www.swissdisk.com/ Ubuntu : http://www.ubuntu.com/ My Blog : http://ben-collins.blogspot.com/ -- 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/
