https://bugzilla.kernel.org/show_bug.cgi?id=201485 --- Comment #2 from aCaB (acab@xxxxxxxxxxxxxxxx) --- Hi, I've got some more time to play with this. First, the ccp messages do NOT appear using modprobe. They are the results of me trying insmod. In fact ccp loads fine: [ 4.482048] ccp 0000:0a:00.2: enabling device (0000 -> 0002) [ 4.484437] ccp 0000:0a:00.2: ccp enabled [ 4.486351] ccp 0000:0a:00.2: enabled [ 4.486386] ccp 0000:42:00.2: enabling device (0000 -> 0002) [ 4.486877] ccp 0000:42:00.2: ccp enabled [ 4.486894] ccp 0000:42:00.2: enabled Second, the "modprobe kvm_amd" behaviour is as follows: With SVM turned OFF in the bios: - v4.15.10: EPERM - v4.16.2: EPERM - v4.17.1: EPERM - v4.17.13: stuck - v4.18.7: stuck With SVM turned ON in the bios: - v4.15.10: ok - v4.16.2: ok - v4.17.1: ok - v4.17.13: stuck - v4.18.7: stuck Before the bios upgrade kvm_amd was loading fine under all the kernel versions above. Unfortunately the flash software has downgrade protection so I can't rollback. -- You are receiving this mail because: You are watching the assignee of the bug.
