They apply a whole series of patches; the combined effect appears to be: - MSI is disabled on QLA24xx chips other than QLA2432 (MSI-X already was) - MSI-X is disabled if qlx2enablemsix=2 - MSI and MSI-X are disabled if qlx2enablemsix=0 The bug report on bugzilla.kernel.org refers to a QLA2422 so that should be covered by the first part. Which board or chip is in these machines? Ben. -- Ben Hutchings The world is coming to an end. Please log off.
