--- Comment #14 from Takashi Iwai
Did you have a working kernel beforehand?
Yes, the same machine on previous installation. I installed OS 13.2 as soon as it was launched, no problem for ~4 months, then I reinstalled it, and give or take few packages, the only major difference is now I used encrypted LVM partition for root. Before reinstall, it worked flawlessly, now it freezes.
The question is what triggered the problem. What's the exact difference from the previous installation?
I guess you misunderstood SysRq. What's here referred to is the "Magic SysRq" keys. The key combo Alt+SysRq+something (on a laptop, it's often with Alt+Fn+Print+something) is captured directly by kernel for special tasks. So it must work no matter which desktop GUI is used.
Should it work when computer is normally working? Because it does not work, I tested it. I get some output only in console, in GUI it was like I didn't press it at all.
Yes, magic sysrq works always. If not, you did something wrong. It doesn't always *show* on console, of course. The kernel log is written to its ring buffer and the daemon logs it to a file and/or show to the console. But the message itself msut be recorded in the ring buffer. -- You are receiving this mail because: You are on the CC list for the bug.
