whereas on 2.6.28 the line "PCI: peer root bus" is no there, instead this is where my USB hubs are detected. -> This PCI: peer root bus updating fails on my machine and lets some PCI devices (in this case my USB) disappear. adding pci=noacpi solved the problem for me, however this seems to be a hack rather than a fix. -- USB disappears after upgrade to 2.6.31 kernel https://bugs.launchpad.net/bugs/464452 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
