(Closes: #990312) I was actually watching the unblock-request bug for that, but apparently it doesn't get updated when the package migrates. I'm in the updated kernel now, and I confirm the fix. gpu_busy_percent is now 0 rather than 99, and the output of 'sensors' for amdgpu-pci-0d00 now reports a fan speed of 815 RPM (down from 1478), temperature readings of 55, 56, and 68 degrees Celsius (down from 66, 72, and 78), and a power reading of 40 W (down from 94). I wasn't hearing/noticing meaningful levels of noise from the fan(s) before, but it does sound just a bit quieter now - and of course less power draw, less heat generation, and less energy consumption are all good things. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

Debian 11 patched kernel is out! That will fix everyone who have been affected and they didn't switched to older kernel or compiled their own. linux-signed-amd64 (5.10.46+3) unstable; urgency=medium * Sign kernel from linux 5.10.46-3 * [armhf] Add mdio-aspeed to nic-modules. Thanks to Joel Stanley (Closes: #991262) * Revert "drm/amdgpu/gfx9: fix the doorbell missing when in CGPG issue." (Closes: #990312) * Revert "drm/amdgpu/gfx10: enlarge CP_MEC_DOORBELL_RANGE_UPPER to cover full doorbell." (Closes: #990312) * Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctl (CVE-2021-3612) * sctp: validate from_addr_param return (CVE-2021-3655) * sctp: add size validation when walking chunks (CVE-2021-3655) * [s390x] sclp_vt220: fix console name to match device (Closes: #961056) * block: return the correct bvec when checking for gaps * sctp: fix return value check in __sctp_rcv_asconf_lookup -- Salvatore Bonaccorso Wed, 28 Jul 2021 07:55:40 +0200 On 24/07/2021 04:32, piorunz wrote: On 23/07/2021 23:44, The Wanderer wrote: https://gitlab.freedesktop.org/drm/amd/-/issues/1632 as being an upstream(?) bug report which covers it.
