Eventually got around to trying out 9.10 Beta live CD - the problem is still here: lockup just before showing the login manager
However I did get an error message early on in the boot process, before the bootsplash logo which said this: [ 0.167144] pci 0000:01:0b.0: BAR 6: address space collision on of device [0xfc9f0000-0xfc97fff] (I don't know what ''on of device'' means but that's exactly what came up) Hopefully this is useful! -- Realtek RTL-8185 based Wifi NIC causes system lockup https://bugs.launchpad.net/bugs/395403 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
