buntu 6.5.0-21.21~22.04.1-generic 6.5.8
** Attachment added: "version.log"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2056303/+attachment/5753222/+files/version.log
** Description changed:
On one Lenovo machine, using a hwe-22.04 kernel, I get several messages
from UBSAN while booting. Previously, on the non-hwe kernel for Jammy,
the screen went black shortly after logging in, and that doesn't seem to
happen any more, so there is improvement, but it seems still something
is going wrong.
Attached are the dmesg (where the UBSAN errors are listed), and the
output from lspci and the version.
+
+ In the dmesg there is this line,
+
+ [ 19.151801] kfd kfd: amdgpu: STONEY not supported in kfd
+
+ which somewhere was indicated that it would be improved in the hwe
+ kernel (that's why I tried it). Apparently the issue isn't fully fixex,
+ but the error seems to be handled better. (Source:
