Hi all, I'm experiencing problem with a HP ProLiant DL360p Gen8 and recent upgrade of 4.13 -> 4.14. dom0 and the entire system becomes unstable and freeze at some point. I've managed to get three pieces of logs (last one after a reboot and just before total freeze) by connecting to the serial console with loglvl options and also redirecting linux kernel output to the serial console: ``` [ 2150.954883] rcu: INFO: rcu_sched detected stalls on CPUs/tasks: [ 2150.954934] rcu: 7-...0: (3 GPs behind) idle=842/1/0x4000000000000000 softirq=64670/64671 fqs=14673 [ 2150.954962] (detected by 12, t=60002 jiffies, g=236593, q=126) [ 2150.954984] Sending NMI from CPU 12 to CPUs 7: [ 2160.968519] rcu: rcu_sched kthread starved for 10008 jiffies! g236593 f0x0 RCU_GP_DOING_FQS(6) ->state=0x0 ->cpu=9 [ 2160.968568] rcu: RCU grace-period kthread stack dump: [ 2160.968586] rcu_sched R running task 0 10 2 0x80004000 [ 2160.968612] Call Trace: [ 2160.968634] ? xen_hypercall_xen_version+0xa/0x20 [ 2160.968658] ? xen_force_evtchn_callback+0x9/0x10 [ 2160.968918] ? check_events+0x12/0x20 [ 2160.968946] ? schedule+0x39/0xa0 [ 2160.968964] ? schedule_timeout+0x96/0x150 [ 2160.968981] ? __next_timer_interrupt+0xd0/0xd0 [ 2160.969002] ? rcu_gp_fqs_loop+0xea/0x2a0 [ 2160.969019] ? rcu_gp_kthread+0xb5/0x140 [ 2160.969035] ? rcu_gp_init+0x470/0x470 [ 2160.969052] ? kthread+0x115/0x140 [ 2160.969067] ? __kthread_bind_mask+0x60/0x60 [ 2160.969085] ? ret_from_fork+0x35/0x40 ``` and also ``` [ 2495.945931] CPU: 14 PID: 24181 Comm: Xorg Not tainted 5.4.72-2.qubes.x86_64 #1 [ 2495.945954] Hardware name: HP ProLiant DL360p Gen8, BIOS P71 05/24/2019 [ 2495.945984] RIP: e030:smp_call_function_many+0x20a/0x270 [ 2495.946004] Code: 8a 00 3b 05 4c b5 69 01 89 c7 0f 83 89 fe ff ff 48 63 c7 49 8b 17 48 03 14 c5 80 f9 3d 82 8b 42 18 a8 01 74 09 f3 90 8b 42 18 <a8> 01 75 f7 eb c9 48 c7 c2 a0 6f 82 82 4c 89 f6 89 df e8 bf b2 8a [ 2495.946051] RSP: e02b:ffffc90003aa7cf0 EFLAGS: 00000202 [ 2495.946068] RAX: 0000000000000003 RBX: 0000000000000010 RCX: 0000000000000007 [ 2495.946090] RDX: ffff8882413ef640 RSI: 0000000000000010 RDI: 0000000000000007 [ 2495.946113] RBP: ffffffff81082fc0 R08: 0000000000000007 R09: 0000000000000000 [ 2495.946134] R10: 0000000000000000 R11: ffffffff8265b6a8 R12: 0000000000000000 [ 2495.946156] R13: 0000000000000001 R14: 0000000000029ac0 R15: ffff8882415a9b00 [ 2495.946211] FS: 00007a0d51a91a40(0000) GS:ffff888241580000(0000) knlGS:0000000000000000 [ 2495.946235] CS: e030 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2495.946253] CR2: 000070abab15a000 CR3: 00000001e18ee000 CR4: 0000000000040660 [ 2495.946290] Call Trace: [ 2495.946314] ? do_kernel_range_flush+0x50/0x50 [ 2495.946334] on_each_cpu+0x28/0x50 [ 2495.946354] decrease_reservation+0x22f/0x310 [ 2495.946377] alloc_xenballooned_pages+0xeb/0x120 [ 2495.946396] ? __kmalloc+0x183/0x260 [ 2495.946413] gnttab_alloc_pages+0x11/0x40 [ 2495.946434] gntdev_alloc_map+0x12f/0x250 [xen_gntdev] [ 2495.946454] gntdev_ioctl_map_grant_ref+0x73/0x1d0 [xen_gntdev] [ 2495.946479] do_vfs_ioctl+0x2fb/0x490 [ 2495.946500] ? syscall_trace_enter+0x1d1/0x2c0 [ 2495.946551] ksys_ioctl+0x5e/0x90 [ 2495.946567] __x64_sys_ioctl+0x16/0x20 [ 2495.946583] do_syscall_64+0x5b/0xf0 [ 2495.946601] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 2495.946620] RIP: 0033:0x7a0d51f763bb [ 2495.946727] Code: 0f 1e fa 48 8b 05 dd aa 0c 00 64 c7 00 26 00 00 00 48 c7 c0 ff ff ff ff c3 66 0f 1f 44 00 00 f3 0f 1e fa b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d ad aa 0c 00 f7 d8 64 89 01 48 [ 2495.946804] RSP: 002b:00007fffc48d5058 EFLAGS: 00000206 ORIG_RAX: 0000000000000010 [ 2495.946863] RAX: ffffffffffffffda RBX: 0000000000001000 RCX: 00007a0d51f763bb [ 2495.946885] RDX: 00007fffc48d5060 RSI: 0000000000184700 RDI: 0000000000000009 [ 2495.946939] RBP: 00007fffc48d5100 R08: 00007fffc48d512c R09: 00007a0d51a30010 [ 2495.946998] R10: 0000000000000000 R11: 0000000000000206 R12: 00007fffc48d5060 [ 2495.947020] R13: 0000000000000001 R14: 0000000000000009 R15: 0000000000000001 [ 2510.964667] rcu: INFO: rcu_sched detected stalls on CPUs/tasks: [ 2510.964716] rcu: 7-...0: (3 GPs behind) idle=842/1/0x4000000000000000 softirq=64670/64671 fqs=96182 [ 2510.964744] (detected by 12, t=420012 jiffies, g=236593, q=11404) [ 2510.964769] Sending NMI from CPU 12 to CPUs 7: [ 2523.945643] watchdog: BUG: soft lockup - CPU#14 stuck for 22s!

I've also observed that some (never the same) VM (PVH or HVM) fail to start randomly because of being stuck at boot time with analog stack trace as the first piece of log provided above. Those VM are impossible to desroy and then it "propagates" though dom0 with the two latest piece of codes. If anyone would have any idea of what's going on, that would be very appreciated. Thank you.
