--- Comment #36 from [email protected] <[email protected]> --- I suffer from the same bug on HP ZBook. However, with the last Debian kernel (ie plain 4.3), I still got an 'error -22' and no "pmu: hw bug workaround enabled" log: $ dmesg | grep nouveau [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.3.0-trunk-amd64 root=/dev/mapper/eyak-root ro nouveau.config=War00C800_0=1 apparmor=1 security=apparmor quiet [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-4.3.0-trunk-amd64 root=/dev/mapper/eyak-root ro nouveau.config=War00C800_0=1 apparmor=1 security=apparmor quiet [ 4.459102] nouveau 0000:01:00.0: enabling device (0000 -> 0003) [ 4.459126] nouveau 0000:01:00.0: NVIDIA GK208 (108390a1) [ 4.462991] nouveau 0000:01:00.0: bios: version 80.28.52.00.09 [ 4.462994] nouveau 0000:01:00.0: mxm: BIOS version 3.0 [ 4.462995] nouveau 0000:01:00.0: bios: unknown ddc map v00 [ 4.463695] nouveau 0000:01:00.0: devinit: 0xce73[0]: unknown opcode 0x00 [ 4.463699] nouveau 0000:01:00.0: preinit failed with -22 [ 4.463718] nouveau: DRM:dddddddd:00000080: init failed with -22 [ 4.464046] nouveau: probe of 0000:01:00.0 failed with error -22 I will put in attachment the result of acpidump on my machine.
