22.693516] NET: Registered PF_QIPCRTR protocol family Whe trying older distros like ubuntu 25.04 or Fedora 42 there is no such cr= ash on same hardware. This crash results in accelerometers not working, so no screen rotation. Also there is issue with suspend/resume when this module crashed. After some search I've came across this patch https://lore.kernel.org/lkml/20250613124648.14141-1-marek.vasut+bmc150@mail= box.org/ rebuilt bmc150-accel-core with this patch and loaded fixed module on Fedo= ra 43. Accelerometer works and no more issues wit suspend/resume. Fedora bugzilla show such issue already was encountered with kernel 6.15.9= =20 https://bugzilla.redhat.com/show_bug.cgi?id=3D2389625 and patch above was disscussed in 6.12 context. --=20 You may reply to this email to add a comment.
