That dmesg is the only that can I get when I plug my wireless, when I plug usb disk the dmesg show me the mount, I can browse the disk and copy some files for a while (about one minute) soon after the system freeze,no more control of keyboard and mouse are available the only things that I can do is force a power restart. Logs do not show any erros. kernel version is: 2.6.17-10-generic This problems comes up only with my DELL C600, with my ASUS P4B533-E same USB disk, same USB camera and same USB wireless works OK. ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- Edgy crashes when USB are plugged on my DELL C600 https://launchpad.net/bugs/76964 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
