On a ProLiant Compute DL384 Gen12 server running Red Hat Enterprise Linux (RHEL) 9.5, after a few reboots, the server may experience a kernel panic, boot to a black screen, and the iLO web page power button shows a "Reset" state.When this occurs, the following kernel panic stack trace is captured:[ 41.223708] Kernel panic - not syncing: Asynchronous SError Interrupt[ 41.223709] CPU: 0 PID: 946 Comm: kworker/0:4 Not tainted 5.14.0-503.11.1.el9_5.aarch64+64k #1[ 41.223710] Hardware name: HPE ProLiant DL384 Gen12/ProLiant DL384 Gen12, BIOS 1.12 10/04/2024[ 41.223711] Workqueue: events aer_recover_work_func[ 41.223713] Call trace:[ 41.223714] dump_backtrace+0xa8/0x120[ 41.223718] show_stack+0x1c/0x30[ 41.223720] dump_stack_lvl+0x74/0x8c[ 41.223723] dump_stack+0x14/0x24[ 41.223724] panic+0x158/0x360[ 41.223726] add_taint+0x0/0xc0[ 41.223729] arm64_serror_panic+0x74/0x84[ 41.223730] do_serror+0x58/0x60[ 41.223731] el1h_64_error_handler+0x38/0x70[ 41.223733] el1h_64_error+0x78/0x7c[ 41.223734] _raw_spin_lock_irqsave+0x40/0xb0[ 41.223736] pci_bus_write_config_word+0x40/0xa0[ 41.223737] pcie_capability_write_word+0x84/0xa0[ 41.223738] pci_restore_state.part.0+0x78/0x250[ 41.223740] pci_restore_state+0x20/0x30[ 41.223742] pci_pm_runtime_resume+0x4c/0x110[ 41.223744] __rpm_callback+0x4c/0x194[ 41.223747] rpm_callback+0x6c/0x7c[ 41.223748] rpm_resume+0x488/0x720[ 41.223750] __pm_runtime_resume+0x5c/0xb0[ 41.223752] pci_pm_runtime_get_sync+0x1c/0x30[ 41.223754] __pci_walk_bus+0x60/0xe0[ 41.223755] pci_walk_bus+0x18/0x20[ 41.223756] pcie_do_recovery+0xa4/0x3a0[ 41.223758] aer_recover_work_func+0x110/0x140[ 41.223759] process_one_work+0x198/0x47c[ 41.223761] worker_thread+0x290/0x394[ 41.223762] kthread+0xe8/0xf4[ 41.223764] ret_from_fork+0x10/0x20[ 41.223767] SMP: stopping secondary CPUs[ 42.271021] SMP: failed to stop secondary CPUs 0,47[ 42.271025] Kernel Offset: 0x404060920000 from 0xffff800080000000[ 42.271025] PHYS_OFFSET: 0x80000000[ 42.271026] CPU features: 0x0,00000003,400b350a,1067fe03[ 42.271027] Memory Limit: none[ 42.863497] ---[ end Kernel panic - not syncing: Asynchronous SError Interrupt ]---
