I have the same issue starting with Linux 2.6.35-rc2 Delan, what type of computer do you see this on? I have a Lenovo Thinkpad x301.
It appears that somehow pressing PrintScr alone trigger the magic SysReq mode. On my laptop normally SysReq is on Fn+PrintScr. But to trigger magic SysReq it is enough to press Alt+PrintScr+<letter>. No Fn is necessary. Now it triggers SysReq with PrintScr alone and waits for the letter. And the keyboard is blocked during that time. Any wrong key then and the system goes down. Pressing Alt again seems to release this mode. -- [Maverick only] Pressing printscreen hangs keyboard https://bugs.launchpad.net/bugs/592042 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
