The log_check WARNINGs with the 4.4 kernels is being addressed by bug
1965160 with commit 036e9ef8becd ("dmaengine: Replace WARN_TAINT_ONCE()
with pr_warn_once()").This commit has been applied upstream for v4.13-rc1, so from bionic+ we should have only the kernel tainted failure. However, that commit keeps the TAINT_FIRMWARE_WORKAROUND taint flag and this is still true for mainline, so probably this bug can't be fixed as this is a hardware issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1912316 Title: log_check / kernel_tainted test from ubuntu_boot failed on Intel Cloud node grumman (failed with flag 2048) Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in linux source package in Xenial: Confirmed Status in linux source package in Bionic: Confirmed Status in linux source package in Focal: Confirmed Status in linux source package in Groovy: Won't Fix Bug description: Issue found on node grumman, this is not a regression.
