[Bug 2156305] Re: OS dmesg log shows 'mpam_msc' errors

Additional information: 1. In the Ubuntu 24.04.3, there are at least two types of complaints shown in the OS demsg: a. Line 2283: [ 16.524691] ACPI MPAM: Bad level (4294967294) for cache with id 0 b. Line 2284: [ 16.530958] mpam_msc mpam_msc.183: probe with driver mpam_msc failed with error -22 2. But none of RHEL 9.6 or 10.0 kernel showed the same error messages errors. 3. Ubuntu 24.04.3 may have different code level of mpam_msc driver incompatible with current ACPI MPAM firmware. 4. Nviaida's own tool passed the MPAM table test. -- You received this bug notification because you are subscribed to linux in Ubuntu.
