as far as I remember, from some old mailing lists email, there is quite a philosophy that you don't need a debugger and using it is a disservice so that's why support is abysmal

I’ve found that sometimes you have to try different VMs, like Virtualbox instead of VMWare. Sometimes the VM itself can be the source of problems, thinking particularly of Virtualbox’s NVME controller with BTRFS. Also, are you doing something specific with Reiser?

Eh, just looking at some fuzzing results. linux-crashdump is getting me static core dumps reliably, but I'm just playing around with being able to dynamically debug the crashes. With a bit less success than I had hoped.

I've had relatively good luck with qemu's `-gdb` flag. pass it a path to make a unix socket and attach to that via gdb's remote target. It's not great, but it's low effort and it works. I can semi reliably reproduce crashes, debug the kernel like a userland process, etc

The best luck I had was with virtualbox and gdb over serial. (This was several years ago though, when towelroot was a thing).

QEMU gdb (not via virtual serial but via QEMU's built-in server)
