[abishai]

It's panicking on 12.0 as well. I use drm-fbsd11.2-kmod as workaround, but I fear that it will stop on recent versions eventually.

[Math2]

I think I'm having the same problem with drm-fbsd-12.0-kmod on 12-STABLE. No panic with drm-fbsd-11.2-kmod. It happens on two different computers with the same Radeon HD 7450 card (it's not supported by the amdgpu driver).

I had filled this bug report about this before: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237544

tl;dr panics with drm-devel-kmod and drm-current-kmod so I'll step down to drm-legacy-kmod (I know, legacy is not intended for use with this hardware but I've had good results with it in the past …)

[grahamperrin]

Today I tested drm-current-kmod from shortly after 10:42 (time of installation) until 17:12 (time of panic).

If it helps, at the time of the panic:

• poudriere in Konsole was building llvm70-7.0.1_4 and llvm80-8.0.1_3
• other running applications included Waterfox, Firefox and SimpleScreenRecorder (recording actions in Firefox).

Files set aside, following the panic, include copies of:

• llvm80-8.0.1_3.log (modified 17:12:12)
• llvm70-7.0.1_4.log (modified 17:12:14).

Message from drm-legacy-kmod-g20190910:

--
The drm-legacy-kmod port can be enabled for older Intel and ATI/AMD graphics
adapters as well as legacy graphics adapters through kld_list in /etc/rc.conf.

Simply add kld_list="/boot/modules/[driver].ko to /etc/rc.conf, for example
kld_list="/boot/modules/i915kms.ko" for the intel GPU driver or
kld_list="/boot/modules/radeonkms.ko" for the ATI/AMD GPU driver.

Please ensure that all users requiring graphics are members of the
"video" group.

If you are having trouble with ATI/AMD graphics cards and X, try installing
xf86-video-ati-legacy instead of xf86-video-ati.

– after which I restarted the OS (reverting to drm-legacy-kmod).

The crash I am having looks the same. If I use fbsd11.2 version, I get an even worse condition: the system triple faults without panicking.

[grahamperrin]

I haven't noticed this type of panic in recent months.

@abishai @Math2 @janicez how are things for you?

[abishai]

@grahamperrin I'm hiding from COVID in secluded village with intel laptop, so it's hard to say if my main box panics or not at the moment. :p

[Math2]

I haven't tried my Radeon HD 7450 with radeonkms in a long time. Right now it's working fine in EFI GOP mode in another 12-STABLE computer that usually doesn't have a screen.

amdgpu is working very well on two computers though. An RX550 on a 12-STABLE desktop that is on pretty much 24/7. And an RX590 on another 13-CURRENT computer (with drm-current-kmod and since a few weeks ago, drm-kmod git master) but it's rebooted often and not always running FreeBSD. But still, it's working very well there too and uptime is sometimes more than a week before the next reboot and no GPU-related problems at all.

No issues of late
