Title: Ubuntu 16.04 4.8.0 kernel crashing on EC2 instances at boot Status in linux package in Ubuntu: Confirmed Bug description: After switching to the linux-hwe kernel on 16.04.2, we started observing kernel crashes on boot on some of our EC2 instances (so far, it only seems to happen on the newer M4 types). The instance becomes unresponsive when this happens. It looks like a rapl issue - we have blacklisted intel_rapl and intel_rapl_perf for now. Here is the trace: general protection fault: 0000 [#1] SMP Modules linked in: intel_rapl_perf(+) i2c_piix4 input_leds parport_pc serio_raw mac_hid parport sch_fq_codel ib_iser rdma_cm iw_cm ib_cm ib_core configfs iscs i_tcp libiscsi_tcp libiscsi scsi_transport_iscsi autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32 c raid1 raid0 multipath linear cirrus crct10dif_pclmul ttm crc32_pclmul drm_kms_helper ghash_clmulni_intel syscopyarea sysfillrect sysimgblt aesni_intel fb_sy s_fops aes_x86_64 lrw glue_helper ablk_helper cryptd drm ixgbevf psmouse pata_acpi floppy fjes CPU: 2 PID: 20 Comm: cpuhp/2 Not tainted 4.8.0-39-generic #42~16.04.1-Ubuntu Hardware name: Xen HVM domU, BIOS 4.2.amazon 11/11/2016 task: ffff8bee465a1d80 task.stack: ffff8bee465ac000 RIP: 0010:[<ffffffffc0728793>] [<ffffffffc0728793>] rapl_cpu_online+0x63/0x71 [intel_rapl_perf] RSP: 0000:ffff8bee465afe18 EFLAGS: 00010212 RAX: 0000000000000200 RBX: ffffffffc0728730 RCX: 0000000000000000 RDX: 0000000000000200 RSI: 0000000000000200 RDI: 0000000000000200 RBP: ffff8bee465afe30 R08: 0000000000000000 R09: 0000000000000001 R10: ffff8bee45ec2600 R11: ffff8bec41fbce00 R12: 6401b4899ff8202c R13: 0000000000000002 R14: ffff8bee4fc0daa0 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff8bee4fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000563b0d9f9dc8 CR3: 000000020608e000 CR4: 00000000001406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Stack: ffffffffc0728730 0000000000000002 000000000000004e ffff8bee465afe70 ffffffff95883d86 ffff8bee4fc0daa0 ffff8bee4fc0daa0 0000000000000002 ffffffff9663df60 ffff8bee464b85f0 ffff8bec47c19300 ffff8bee465afe90 Call Trace: [<ffffffffc0728730>] ?
