> the current design of KPROBES enforces execution under IRQs being disabled. Is this also the case when kprobes get optimized to ftrace, though?

@udovdh You can try the `mem=16G` kernel parameter. However, I'm sure there are others who use LKRG on 32+ GB. I have LKRG on a 32 GB machine, but that...

@udovdh Please don't spam Linux kernel upstream developers with issues likely related to LKRG or our experiments with it. Yes, that crash you reference looks related to our attempted use...

@udovdh Can you show your kernel config, and in particular lines with `FTRACE` on them?

@udovdh Please try enabling `CONFIG_FTRACE`. For this test, we need to have more than just the `HAVE` versions of the sub-options enabled.

@udovdh Probably correct, yes. Can you show the resulting `.config` lines?

@udovdh Should be good enough. Please proceed to test this.

@udovdh Did 5.15.8 crash for you even after you enabled ftrace?

@udovdh I notice you've added more messages to the linux-kernel thread, instead of to here. Please stop spamming upstream Linux developers with an issue that isn't theirs. Really. You might...
