It's always 021d202d (3 times) and always where a vma might be accessed (a /proc file, khugepaged(), acct_collect()) so I would assume a struct vma was corrupted in the hibernate/resume process. Could be also firmware related AFAIK and there's I taint flag which means some buggy firmware workaround is in effect. > Oct 23 13:22:10 linuxp dhcpcd[18199]: dhcpcd not running > Oct 23 15:55:49 linuxp dhcpcd[27045]: dhcpcd not running > Oct 23 15:55:49 linuxp dhcpcd[27053]: dhcpcd not running > Oct 23 15:55:50 linuxp dhcpcd[27061]: dhcpcd not running > Oct 23 15:55:50 linuxp dhcpcd[27067]: dhcpcd not running > Oct 23 17:31:13 linuxp kernel: [140897.356150] iwlwifi 0000:03:00.0: > RF_KILL bit toggled to enable radio. > Oct 23 17:31:16 linuxp kernel: [140900.724013] Bluetooth: hci0: > unexpected event for opcode 0xfc2f > Oct 23 17:31:39 linuxp kernel: [140928.245135] BUG: unable to handle > page fault for address: 021d2001 > Oct 23 17:31:39 linuxp kernel: [140928.245147] #PF: supervisor read > access in kernel mode > Oct 23 17:31:39 linuxp kernel: [140928.245152] #PF: error_code(0x0000) - > not-present page > Oct 23 17:31:39 linuxp kernel: [140928.245169] Oops: 0000 [#1] SMP PTI > Oct 23 17:31:39 linuxp kernel: [140928.245179] CPU: 1 PID: 2302 Comm: > Breakpad Server Tainted: G I 5.9.1 #1 > Oct 23 17:31:39 linuxp kernel: [140928.245184] Hardware name: > Notebook W65_W67RZ/W65_W67RZ, BIOS 1.05.06 > 02/22/2016 > Oct 23 17:31:39 linuxp kernel: [140928.245197] EIP: m_next+0x1c/0x44 > Oct 23 17:31:39 linuxp kernel: [140928.245205] Code: 24 08 d4 e6 c1 e8 > 1a 77 e2 ff eb d6 cc cc 3e 8d 74 26 00 55 89 e5 57 56 53 8b 40 44 8b 58 > 0c 39 da 74 24 8b 42 08 85 c0 74 0e <8b> 30 31 ff 89 31 89 79 04 5b 5e > 5f 5d c3 be ff ff ff ff 31 ff 85 > Oct 23 17:31:39 linuxp kernel: [140928.245212] EAX: 021d2001 EBX: > 00000000 ECX: eeb9e56c EDX: eca0f000 > Oct 23 17:31:39 linuxp kernel: [140928.245216] ESI: 00000000 EDI: > c128cad0 EBP: e59bff0c ESP: e59bff00 > Oct 23 17:31:39 linuxp kernel: [140928.245221] DS: 007b ES: 007b FS: > 00d8 GS: 00e0 SS: 0068 EFLAGS: 00010202 > Oct 23 17:31:39 linuxp kernel: [140928.245224] CR0: 80050033 CR2: > 021d2001 CR3: 2606c000 CR4: 003506f0 > Oct 23 17:31:39 linuxp kernel: [140928.245228] DR0: 00000000 DR1: > 00000000 DR2: 00000000 DR3: 00000000 > Oct 23 17:31:39 linuxp kernel: [140928.245231] DR6: fffe0ff0 DR7: 00000400 > Oct 23 17:31:39 linuxp kernel: [140928.245233] Call Trace: > Oct 23 17:31:39 linuxp kernel: [140928.245242] ?

It seem's that you are right concerning the buggy firmware. Here are lines at start in syslog : [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0xb2 (or later) MDS CPU bug present and SMT on, data leak possible.
