One thing about alt sysreq, once you get to a certain point, you have
to go "all the way" with it. I've found that just the R and E generally
gets things back to a point it is accessible and I don't have to go
through it all. I think once you get to the I or S, it's all or nothing
at that point. Even after the E, you may have to start/restart some
init processes. FYI, I'm pretty sure the S is what syncs the file
systems and the U unmounts everything. Of course, the B reboots. I
can't recall what the others do exactly.
With access to the kernel sources, you doesn’t have to remember what the
others do, see ‘/usr/src/linux/Documentation/admin-guide/sysrq.rst’.
