From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.9-e.3enterprise i686) Description of problem: Alt-Sysrq handling on ia64 in general is spotty at best. Typically upon entering Alt-Sysrq with a supported key, it displays only the help message, as if an incorrect key were pressed; then it stays in that mode with any subsequent key entry, repeating the help message. Eventually it may/will "get out" of the loop and perform the request. Version-Release number of selected component (if applicable): kernel-2.4.18-e.25 How reproducible: Sometimes Steps to Reproduce: 1. Enter Alt-Sysrq-T (or any other supported key) 2. 3. Actual Results: The help string is displayed and then repeatedly displays with subsequent keystrokes: Sysrq: HELP : loglevl0-8 reBoot tErm kIll saK showMem Off showPc unRaw Sync showTasks Unmount ... Expected Results: The correct "Sysrq : xxxx" string for the key entered should be displayed and the command initiated. Additional info:
Out of curiousity - usb keyboard?
yes, usb...
Does a USB keyboard on x86 show the same problem for you? I've seen something similar with a USB keyboard on x86 and sysrq, so I wonder if it's a USB issue and not an ia64 issue.
Good question -- we just tried it on one x86 box here, and it worked OK.
