Sorry, I found that if I waited for about 10 minutes I get that error message about the USB again:

(note that this is what GDM runs when it starts) Yet with pci=noacpi option it is normal ! -- booting HP Pavilion tx1020 laptop requires noapic kernel option https://bugs.launchpad.net/bugs/103273 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
