This laptop was previously running distro kernel 2.6 (2.6.27.9-159.fc10.i686) without any trouble. While listening to audio, after a few minutes (10-15) the audio will loop. I can most times move the mouse and click on windows but no new process will start in reasonable time and the terminal will repeat each key twice (type d and it will take dd for example) and thus no command can be executed. I tried pre-entering various useful sysrq commands (t, l, d, u,c) and tried hitting enter after reproducing the problem but that command goes nowhere. Even shutdown button which normally pops up the Gnome shutdown dialog will do nothing. Machine isn't pingable. The problem is 100% reproducible - I just can't figure out a good way to get some debug data out. This laptop doesn't have a serial and doesn't have the sysrq key, so I was thinking about using the USB Serial adapter - will USB serial console via null modem cable work here if I build in the driver for the USB-Serial dongle and set the right config options? (Found the usb-serial dongle in the basement but null modem cable is yet to be arranged.)
