There seems to be some sort of hardware problem or race condition because this problem only seems to happen when I turn the computer on from cold, no matter which kernel version I use. If I do a warm reboot then it almost never happens. I've never known the problem to go away without a reboot once it has manifested itself, nor for that matter to manifest itself without a reboot if it hasn't at the start. It's not causing me serious issues any more because I just check it works when I first boot up and, if not, reboot again and 9 times out of 10 it fixes it, but it's still a little annoying, and my curiosity would like to get to the bottom of what's causing it! -- Andy Buchanan e-mail: a...@buchanans.org.uk tel.: 020 8651 1886 mob.: 07940 525 612 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/698099 Title: OX16PCI954 ttyS0 non-functional regression -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
