[Bug 267028] General protection fault kernel panic immediately after kldload amdgpu

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #23 from George Mitchell --- Thanks! So far, I've booted four times with amdgpu in my kld_list, which previously would likely have yielded at least one crash, with no crash. So I have my fingers crossed, but I'll try your hack

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #22 from Graham Perrin --- (In reply to George Mitchell from comment #21) If a crash _does_ occur/recur, then maybe test for reproducibility with this in your /boot/loader.conf kern.smp.disabled=1

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #20 from George Mitchell --- I've figured out why this crash is timing related, and also why ZFS is involved. My system has a 1 TB USB disk, which contains a ZFS file system. When I power my system on, it takes a variable amou

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #18 from George Mitchell --- I hate to say again how little I know about kernel module loading, but by any chance is there multithreading in the code that gets called when amdgpu.ko is first loaded? I can't help thinking that p

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #17 from George Mitchell --- I've discovered how to avoid this crash (at least the last 20-30 times I have booted up): boot into single user mode, type to run /bin/sh, type "kldload amdgpu," and then (key step!) wait at least f

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #16 from George Mitchell --- The following comment is based on zero actual knowledge of how kernel loadable modules work. Still, based on what I'm seeing with this bug, I hypothesize that after one module is loaded, there is a

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #12 from George Mitchell --- Without amdgpu in the kld_list, kld_list currently is not even defined. Perhaps it's more helpful to show what gets loaded aside from amdgpu int he course of a normal boot: kldstat 1 64 0xff

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #8 from George Mitchell --- Thanks for the work so far. "zfs" is not explicitly in the kld_list, but I do use ZFS and zfs_enable is set to "YES". Also: tunefs: POSIX.1e ACLs: (-a)disabled tunef
