That’s interesting, I doesn’t expect that. Maybe we are using different |
| 26 |
kernel sources. Mine is ‘sys-kernel/gentoo-sources-4.10.12::gentoo’ but |
| 27 |
wait, I’ve found it also under ‘Documentation/sysrq.txt’ with version |
| 28 |
4.9.16 and it’s slightly a little bit different (in form not in content |
| 29 |
as far as I can see). |

Ha, yes of course, a paper backup beats them all (under typical |
