Hi, I also got some hardware refusing to boot with this bug : HP ProLiant DL360 Gen9
The crash is instant, right after GRUB loads the kernel and initramfs. Partial backtrace (re-typed from a KVM screen capture) : [ 0.649289] Call Trace: [ 0.649362] [<ffffffff8192332c>] ? sched_init_smp+0x398/0x452 [ 0.649437] [<ffffffff815244de>] ? mutex_lock+0xe/0x2a [ 0.649512] [<ffffffff81069b23>] ? put_online_cpus+0x23/0x80 [ 0.649587] [<ffffffff810f284c>] ? stop_machine+0x2c/0x40 [ 0.649662] [<ffffffff8190415e>] ? kernel_init_freeable+0xdd/0x1e1 [ 0.649738] [<ffffffff81512c00>] ? rest_init+0x80/0x80 [ 0.649813] [<ffffffff81512c0a>] ? kernel_init+0xa/0xf0 [ 0.649888] [<ffffffff81525c58>] ? ret_from_fork+0x58/0x90 [ 0.649963] [<ffffffff81512c00>] ? rest_init+0x80/0x80 [ 0.650037] Code: c0 0f 85 46 05 00 00 48 8b 74 24 08 48 c7 c2 00 dd a6 81 bf ff ff ff ff e8 91 78 21 00 48 98 49 8b 56 10 48 8b 04 c5 a0 1e 8e 81 <48> 8b 14 10 b8 01 00 00 00 49 89 54 24 10 f0 0f c1 02 85 c0 75 [ 0.653853] RIP [<ffffffff8109be3d>] build_sched_domains+0x72d/0xcf0 [ 0.653986] RSP <ffff8802774f3df8> [ 0.654061] ---[ end trace 5d1a1ddbcedef31d ]--- [ 0.654145] Kernel panic - not syncing: Attempted to kill init! exit code=0x0000000b [ 0.654145] [ 0.654252] ---[ end Kernel panic - not syncing: Attempted to kill init! exit code=0x0000000b [ 0.654252] I could only fix the issue by downgrading. It should be noted that even after the downgrade, it reports this error, if there is any chance of relevance : [ 0.059876] [Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 38d is 330) Cheers, -- ラピー ステファン Lapie Stephane 株式会社朝日ネット システム部 AsahiNet, Inc. - System Division
