Hi, I recently saw my Alderlake NUC spewing on boot: [ 13.166514] irq 109: nobody cared (try booting with the "irqpoll" option) [ 13.166614] CPU: 5 PID: 0 Comm: swapper/5 Not tainted 6.3.0+ #66 [ 13.166694] Hardware name: LENOVO 30FBS0B800/330E, BIOS M4GKT18A 04/26/2022 [ 13.166779] Call Trace: [ 13.166812] <IRQ> [ 13.166840] dump_stack_lvl+0x5b/0x90 [ 13.166891] __report_bad_irq+0x2b/0xc0 [ 13.166941] note_interrupt+0x2ac/0x2f0 [ 13.166991] handle_irq_event+0x6f/0x80 [ 13.167041] handle_fasteoi_irq+0x94/0x1f0 [ 13.167093] __common_interrupt+0x72/0x160 [ 13.167112] intel_rapl_common: Found RAPL domain package [ 13.167141] common_interrupt+0xb8/0xe0 [ 13.167200] intel_rapl_common: Found RAPL domain core [ 13.167242] </IRQ> [ 13.167297] intel_rapl_common: Found RAPL domain uncore [ 13.167322] <TASK> [ 13.167437] asm_common_interrupt+0x26/0x40 [ 13.167492] RIP: 0010:cpuidle_enter_state+0xff/0x500 [ 13.167554] Code: c0 48 0f a3 05 72 34 ad 01 0f 82 fc 02 00 00 31 ff e8 35 b3 52 ff 45 84 ff 0f 85 cc 02 00 00 e8 f7 13 64 ff fb 0f 1f 44 00 00 <45> 85 f6 0f 88 eb 01 00 00 49 63 d6 48 8d 04 52 48 8d 04 82 49 8d [ 13.167766] RSP: 0018:ffffc900001ebe90 EFLAGS: 00000206 [ 13.167843] RAX: 000000000012a8f3 RBX: ffffe8ffff480a00 RCX: 0000000000000000 [ 13.167928] RDX: 0000000000000000 RSI: ffffffff8244c6ee RDI: ffffffff8242ca22 [ 13.168021] RBP: 0000000000000001 R08: 0000000000000001 R09: 0000000000000001 [ 13.168105] R10: 0000000000000003 R11: 000000000000000a R12: ffffffff83625a80 [ 13.168189] R13: 0000000310c8ee5e R14: 0000000000000001 R15: 0000000000000000 [ 13.168289] cpuidle_enter+0x2d/0x40 [ 13.168339] do_idle+0x231/0x290 [ 13.168383] cpu_startup_entry+0x1d/0x20 [ 13.168432] start_secondary+0x11b/0x140 [ 13.168482] secondary_startup_64_no_verify+0xf9/0xfb [ 13.168549] </TASK> [ 13.168587] handlers: [ 13.168617] [<00000000497ef927>] irq_default_primary_handler threaded [<00000000cf102de1>] tis_int_handler [ 13.168767] Disabling IRQ #109 this is apparently: root@alderlake:~# cat /proc/interrupts | grep 109 109: 0 0 0 0 0 100002 0 0 0 0 0 0 0 0 0 0 0 0 0 0 00 0 0 IR-IO-APIC 109-fasteoi tpm0 the TPM thing, which per same dmesg above is: [ 10.948058] tpm_tis MSFT0101:00: 2.0 TPM (device-id 0x1D, rev-id 54) Booting with tpm_tis.interrupts=0 seems to cure things, and AFAICT the tpm device actually works -- that is, tpm2 getcap -l and tpm2 pcrread both give output, I'm presuming this is 'good'. I've never operated a TPM before. The machine in question is: Manufacturer: LENOVO Product Name: 30FBS0B800 Version: ThinkStation P360 Tiny So I'm thinking that perhaps Lenovo carried the bug mentioned in commit: b154ce11ead9 ("tpm_tis: Disable interrupts on ThinkPad T490s") to more products.
