I'm not sure which commit you are referring to, but the one which causes this type of failure is: c3164d2e0d18 ("PCI/MSI: Convert pci_msi_ignore_mask to per MSI domain flag") which is fixed by 3ece3e8e5976 ("PCI/MSI: Handle the NOMASK flag correctly for all PCI/MSI backends") i.e. this pull request. > Full logs of the run are available at: > https://qa-reports.linaro.org/lkft/sashal-linus-next/build/v6.13-rc7-16083-gc13edfd29c29/testrun/27775255/suite/log-parser-test/test/bug-bug-kernel-null-pointer-dereference-address/details/ TBH, and I know this is not your fault, this report page is a masterpiece of bad engineering. It contains tons of useless information, but fails to provide the most important basic data: 1) There is no date of the failure Am I supposed to reverse engineer this out of this horrible user interface? I haven't even found a way to figure it out within a reasonable time. I just gave up. 2) There is no useful reference to the actually used source tree and commit v6.13-rc7-16083-gc13edfd29c29 is _NOT_ a helpful reference as it suggests that this is a 6.13-rc7 based tree, but the log file says: Linux version 6.14.0 sasha-linus-next at least gives a hint where to rumage, and 100 clicks later I'm able to see what this is actually testing. Seriously? Thanks, tglx
