Yes, the Alt-SysRq + 1-4,7-9,0 keys do nothing on mine as well, even on the plain console. But if I send the numbers to sysrq-trigger, then it works. So probably it's a separate bug report. I've 1 in sysrq. $ cat /proc/sys/kernel/sysrq 1 So in summary the process is killed if the key is not

Hi Bob, thanks for the reminder, but I didn't receive any message from Alan, could you re-post it? Maybe it went to Spam. Is there any web version of this bug tracker? At work they're blocking the access for all the emails. Kind Regards, Rafal Sent from my iPhone On 30 Sep 2012, at 07:40, Bob

Yes, I've tried and it didn't QUIT (it ignored SysRq signal). I didn't know about Ctrl-4 shortcut for sending the QUIT signal. After that I had to kill the process, because Control-D didn't work. So I'm assuming it's by design. Thanks for your help. Kind Regards, Rafal Sent from my iPhone On 30

But if Control-4 is sending QUIT signal, why: Control-1 does kill the process? I've checked again and actually it's not even about the number. When I press only: Control-SysRq it kills the process as well. Sometimes it happens on press, sometimes on release. Kind Regards, Rafal Sent from my

Hi, Thanks for this info. Just to explain why I press it with Control and Alt. My Linux freezing all the time, so sometimes I'm using kernel SysRq for the reason. So in example if I want to check all currently held Locks with SysRq-D (which doesn't work anyway), so: When I press SysRq-D, I've

Thanks. Without Control more things are working. Alt-SysRq-m and other letters works, doesn't kill the process. So the only problems are numbers: Alt-SysRq-1 to 9 (exempt 5 6) is killing the process. Looks like 5 and 6 have some special privileges. Kind Regards, Rafal Sent from my iPhone On 1
