Hello, With a new installation of Rocky 9.5 using a 6.11.7 kernel we have observed a system crash related to the unloading/loading of the mt7915e kernel module, using the MT7916 hardware. Included below is the output of a kernel warning during unload. The system crashes during module load, and so no log output is available. I’ve also included version information. Usually at most 3-5 cycles of unload/load are needed to generate a crash. (e.g. `modprobe -r mt7915e && modprobe mt7915e`). Would anyone be able to debug this with me? I would be happy to provide more debugging or logging information as needed. Thank you, Tim Carlin QA Cafe Dec 3 11:06:14 localhost kernel: mt7915e 0000:51:00.0: HW/SW Version: 0x8a108a10, Build Time: 20230202144915a Dec 3 11:06:14 localhost kernel: mt7915e 0000:51:00.0: WM Firmware Version: ____000000, Build Time: 20230202145005 Dec 3 11:06:14 localhost kernel: mt7915e 0000:51:00.0: WA Firmware Version: DEV_000000, Build Time: 20230202143332 Dec 3 11:09:45 localhost kernel: ------------[ cut here ]------------ Dec 3 11:09:45 localhost kernel: WARNING: CPU: 16 PID: 2952 at net/core/page_pool.c:1057 page_pool_disable_direct_recycling+0x33/0x40 Dec 3 11:09:45 localhost kernel: Modules linked in: snd_seq_dummy(E) snd_hrtimer(E) snd_seq(E) snd_seq_device(E) snd_timer(E) snd(E) soundcore(E) nft_fib_inet(E) nft_fib_ipv4(E) nft_fib_ipv6(E) nft_fib(E) nft_reject_inet(E) nf_reject_ipv4(E) nf_reject_ipv6(E) nft_reject(E) nft_ct(E) nft_chain_nat(E) nf_nat(E) nf_conntrack(E) nf_defrag_ipv6(E) nf_defrag_ipv4(E) ip_set(E) nf_tables(E) nfnetlink(E) qrtr(E) vfat(E) fat(E) intel_rapl_msr(E) intel_rapl_common(E) intel_uncore_frequency(E) intel_uncore_frequency_common(E) i10nm_edac(E) skx_edac_common(E) nfit(E) libnvdimm(E) x86_pkg_temp_thermal(E) intel_powerclamp(E) coretemp(E) iwlmvm(E) kvm_intel(E) mt7915e(E-) mt76_connac_lib(E) mt76(E) kvm(E) mac80211(E) iwlwifi(E) rapl(E) libarc4(E) intel_cstate(E) cfg80211(E) iTCO_wdt(E) intel_pmc_bxt(E) iTCO_vendor_support(E) isst_if_mbox_pci(E) isst_if_mmio(E) ipmi_ssif(E) intel_uncore(E) dax_hmem(E) pcspkr(E) isst_if_common(E) i2c_i801(E) rfkill(E) i2c_mux(E) ftdi_sio(E) intel_th_gth(E) mei_me(E) i2c_smbus(E) mei(E) intel_pch_thermal(E) intel_th_pci(E) Dec 3 11:09:45 localhost kernel: intel_vsec(E) ioatdma(E) intel_th(E) ipmi_si(E) acpi_power_meter(E) acpi_ipmi(E) ipmi_devintf(E) joydev(E) ipmi_msghandler(E) acpi_pad(E) xfs(E) libcrc32c(E) rndis_host(E) cdc_ether(E) usbnet(E) mii(E) sd_mod(E) sg(E) ast(E) drm_shmem_helper(E) drm_kms_helper(E) crct10dif_pclmul(E) ahci(E) crc32_pclmul(E) crc32c_intel(E) polyval_clmulni(E) libahci(E) polyval_generic(E) nvme(E) drm(E) libata(E) igb(E) i40e(E) ghash_clmulni_intel(E) nvme_core(E) libie(E) dca(E) i2c_algo_bit(E) fuse(E) Dec 3 11:09:45 localhost kernel: CPU: 16 UID: 0 PID: 2952 Comm: modprobe Kdump: loaded Tainted: G W E 6.11.7-1.el9.elrepo.x86_64 #1 Dec 3 11:09:45 localhost kernel: Tainted: [W]=WARN, [E]=UNSIGNED_MODULE Dec 3 11:09:45 localhost kernel: Hardware name: Supermicro Super Server/X12SPL-F, BIOS 1.9 01/03/2024 Dec 3 11:09:45 localhost kernel: RIP: 0010:page_pool_disable_direct_recycling+0x33/0x40 Dec 3 11:09:45 localhost kernel: Code: c7 47 30 ff ff ff ff 48 85 c0 74 19 48 8b 50 10 83 e2 01 74 15 8b 40 34 83 f8 ff 75 11 48 c7 47 18 00 00 00 00 c3 cc cc cc cc <0f> 0b eb e7 0f 0b eb eb 0f 1f 44 00 00 90 90 90 90 90 90 90 90 90 Dec 3 11:09:45 localhost kernel: RSP: 0018:ff5df22286b17d78 EFLAGS: 00010246 Dec 3 11:09:45 localhost kernel: RAX: ff375ee85b302f90 RBX: ff375ee850031800 RCX: 0000000000000000 Dec 3 11:09:45 localhost kernel: RDX: 0000000000000000 RSI: ffffffff937e54ce RDI: ff375ee850031800 Dec 3 11:09:45 localhost kernel: RBP: ff375ee85b302020 R08: 0000000000000000 R09: ff5df22286b17d57 Dec 3 11:09:45 localhost kernel: R10: 0000000000000000 R11: 0000000000000187 R12: ff375ee85b303120 Dec 3 11:09:45 localhost kernel: R13: ff375ee85b304dd0 R14: ff375ee85b3026b8 R15: ffffffffc09d99b8 Dec 3 11:09:45 localhost kernel: FS: 00007f5bc1182740(0000) GS:ff375ef73fc00000(0000) knlGS:0000000000000000 Dec 3 11:09:45 localhost kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Dec 3 11:09:45 localhost kernel: CR2: 0000563961080000 CR3: 000000011eafe006 CR4: 0000000000771ef0 Dec 3 11:09:45 localhost kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Dec 3 11:09:45 localhost kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Dec 3 11:09:45 localhost kernel: PKRU: 55555554 Dec 3 11:09:45 localhost kernel: Call Trace: Dec 3 11:09:45 localhost kernel: <TASK> Dec 3 11:09:45 localhost kernel: ?
