… better without drm-next-kmod; and (as expected, given the package message)
drm-stable-kmod has known problems with UEFI.
Now (with r339186) it seems that drm-next-kmod is the only usable option.
However, I'm sorry to say:
- it does feel regressive, compared to working without drm-next-kmod with
earlier versions of -CURRENT.
I can no longer find a way to reliably suspend (sleep) the notebook.
hey Graham - I'm struggling with suspend/resume issues as well on my end
with recent 12-ALPHA releases. can you verify that you can
suspend/resume without loading the radeonkms.ko (i believe that is what
you are using for gfx)? on my systems it's broken regardless if i load
the drm modules.
also, what was the last version of CURRENT you were able to
suspend/resume with?
At the time of writing my part-working configuration is as outlined below.
However – frustratingly – for a while, an hour or so ago, it seemed as if the
same configuration was useless; after a point, the screen would go blank (grey)
and things would progress no further e.g. no login manager (sddm); no response
to Control-Alt-F2; no response to Control-Alt-Delete. The apparent
unpredictability leading to a dead-end situation has created a sense of unease;
now I'm genuinely afraid to test suspend :-(
i believe johannes lundberg is working on a fix for this issue. i'm in
the same uneasy situation as you. the system i use for dogfooding is
also my main work laptop, and not having suspend/resume and other
instability like this is certainly not ideal. one potential fix
workaround we've found is to not load the module via "kld_list" but
rather load it by hand via "kldload" manually. i believe the bug is in
relation to how the BIOS allocates memory - i'll let him fill in details :)
for me at least it looks like system instability when loading drm-next
kernels is separate from suspend/resume. but its certainly possible my
laptop is a snowflake :p
hope this helps.
