Alt-Sysrq handling is inconsistent

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):
Steps to Reproduce:
1. Enter Alt-Sysrq-T (or any other supported key)
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
Expected Results: The correct "Sysrq : xxxx" string for the key entered should
be displayed and the command initiated.
Out of curiousity - usb keyboard?
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.
