Since then, "modprobe kvm_amd" gets stuck forever. It won't fail nor succeed. Strace gets stuck at: openat(AT_FDCWD, "/lib/modules/4.18.7-flaw/kernel/drivers/crypto/ccp/ccp.ko", O_RDONLY|O_CLOEXEC) = 3 read(3, "\177E", 2) = 2 lseek(3, 0, SEEK_SET) = 0 fstat(3, {st_mode=S_IFREG|0644, st_size=133408, ...}) = 0 mmap(NULL, 133408, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7fbf21eb1000 finit_module(3, "", 0 When the command runs there are no output nor kernel.log/dmesg log entries produced, however, once per boot, i get a series of these: Oct 22 12:25:20 flawless kernel: [ 2362.710015] kvm_amd: gave up waiting for init of module ccp.
