I have the same issue. Ubuntu kernel 2.6.19-x hangs during boot after usb related messages. But I don't know the real problem or can't make any dump or logs. Alt+sysrq+t works but it scrolls over the limit of shift+pageup and I can't read all the message.
What can I do? I'll attach my lshw. ** Attachment added: "Output of lshw" http://librarian.launchpad.net/5041122/lshw -- kernel hangs for a few seconds during boot https://launchpad.net/bugs/70917 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
