Since rc6 I am getting crashes in JetBrain's Rider backend for CLion, which the backend is a C# application specifically, which gives in its logs: ``` Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ``` Unfortunately, I do not see any traces in `dmesg` at all and there is not much else useful there. Since this is a closed source application, I cannot do much in debugging it unfortunately. It manifests as a never completing analyzation pass. Unlike David Wang, I am on an Intel Core i7-1370P on a ThinkPad X1 Yoga Gen 8 (with TME) and I have not experienced any crashes with GDB or Go in any way, nor other program issues at all. I have not experienced any issues with rc3 (which is what I was previously using as I often check for updates every so often). Unrelated to this, after suspending and docking my laptop to my dock, I get this now: [50598.774359] ------------[ cut here ]------------ [50598.774371] kernfs: can not remove 'typec', no directory [50598.774389] WARNING: CPU: 2 PID: 48932 at fs/kernfs/dir.c:1706 kernfs_remove_by_name_ns+0xcf/0xe0 [50598.774404] Modules linked in: snd_usb_audio snd_usbmidi_lib snd_rawmidi mptcp_diag xsk_diag tcp_diag udp_diag raw_diag inet_diag unix_diag af_packet_diag netlink_diag xpad(O) xt_conntrack xt_MASQUERADE xt_set ip_set xt_addrtype xfrm_user xfrm_algo snd_seq_dummy snd_hrtimer snd_seq snd_seq_device nls_utf8 cifs cifs_md4 dns_resolver netfs iscsi_tcp nft_masq libiscsi_tcp libiscsi scsi_transport_iscsi target_core_user uio target_core_pscsi target_core_file target_core_iblock iscsi_target_mod target_core_mod xt_tcpudp nft_compat x_tables nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 rfcomm nf_tables qrtr at24 ee1004 bnep snd_ctl_led snd_soc_skl_hda_dsp snd_soc_intel_sof_board_helpers snd_soc_intel_hda_dsp_common snd_sof_probes vhba(O) snd_hda_codec_intelhdmi br_netfilter snd_hda_codec_alc269 bridge snd_hda_scodec_component stp snd_hda_codec_realtek_lib snd_soc_dmic llc snd_hda_codec_generic [50598.774515] snd_hda_intel pkcs8_key_parser snd_sof_pci_intel_tgl snd_sof_pci_intel_cnl snd_sof_intel_hda_generic soundwire_intel soundwire_generic_allocation snd_sof_intel_hda_sdw_bpt snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda_mlink snd_sof_intel_hda snd_hda_codec_hdmi soundwire_cadence snd_sof_pci snd_sof_xtensa_dsp snd_sof snd_soc_avs snd_sof_utils snd_soc_hda_codec snd_soc_acpi_intel_match snd_hda_ext_core snd_soc_acpi_intel_sdca_quirks snd_hda_codec uvcvideo nls_ascii snd_soc_acpi snd_hda_core videobuf2_vmalloc nls_cp437 crc8 snd_intel_dspcfg btusb uvc intel_uncore_frequency soundwire_bus snd_intel_sdw_acpi btmtk hid_sensor_accel_3d hid_sensor_custom_intel_hinge hid_sensor_gyro_3d videobuf2_memops intel_uncore_frequency_common snd_soc_sdca snd_hwdep btrtl hid_sensor_trigger videobuf2_v4l2 coretemp snd_soc_core btbcm intel_pmc_core hid_sensor_iio_common videodev rapl mei_hdcp mei_pxp snd_compress btintel pmt_telemetry industrialio_triggered_buffer videobuf2_common intel_cstate spi_nor iosm [50598.774603] snd_pcm_dmaengine mei_me pmt_discovery bluetooth kfifo_buf mc intel_uncore pcspkr mtd wwan snd_pcm mei pmt_class button igen6_edac mei_vsc_hw soc_button_array ac acpi_pad industrialio intel_pmc_ssram_telemetry acpi_tad snd_timer joydev evdev snd soundcore hid_xpadneo(O) ff_memless parport_pc ppdev lp parport efi_pstore nvme_fabrics loop nfnetlink zram 842_decompress 842_compress autofs4 hid_sensor_custom hid_multitouch psmouse i2c_i801 hid_sensor_hub i2c_hid_acpi serio_raw i2c_smbus hid_generic i2c_hid [50598.774677] CPU: 2 UID: 0 PID: 48932 Comm: kworker/2:1 Tainted: G O 6.18.0-rc6 #5 PREEMPT(full) [50598.774688] Tainted: [O]=OOT_MODULE [50598.774691] Hardware name: LENOVO 21HQCTO1WW/21HQCTO1WW, BIOS N3XET62W (1.37 ) 07/28/2025 [50598.774696] Workqueue: events ucsi_handle_connector_change [50598.774708] RIP: 0010:kernfs_remove_by_name_ns+0xcf/0xe0 [50598.774715] Code: 5b 5d 41 5c 41 5d c3 cc cc cc cc 48 89 ef e8 98 1a c0 ff b8 fe ff ff ff eb e6 0f 0b eb 9f 48 c7 c7 b0 5e dc 9d e8 21 42 b7 ff <0f> 0b eb e5 66 66 2e 0f 1f 84 00 00 00 00 00 66 90 90 90 90 90 90 [50598.774721] RSP: 0018:ffffcf1ecce83db8 EFLAGS: 00010282 [50598.774727] RAX: 0000000000000000 RBX: ffff8c645507d400 RCX: 0000000000000027 [50598.774732] RDX: ffff8c709f298a48 RSI: 0000000000000001 RDI: ffff8c709f298a40 [50598.774736] RBP: ffff8c61825ad008 R08: 0000000000000000 R09: ffff8c70df772fe8 [50598.774740] R10: ffff8c70df742fa8 R11: 0000000000000003 R12: ffffffff9dfaadb1 [50598.774743] R13: ffff8c61825ad350 R14: 0000000000000001 R15: ffff8c6182582520 [50598.774746] FS: 0000000000000000(0000) GS:ffff8c70ffd3d000(0000) knlGS: 0000000000000000 [50598.774751] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [50598.774755] CR2: 00007f9af0c6f000 CR3: 000000099464c003 CR4: 0000000000f72ef0 [50598.774760] PKRU: 55555554 [50598.774763] Call Trace: [50598.774768] [50598.774775] typec_unregister_partner+0x6c/0x110 [50598.774787] ucsi_unregister_partner+0x103/0x140 [50598.774794] ucsi_handle_connector_change+0x34d/0x3e0 [50598.774803] process_one_work+0x18b/0x340 [50598.774811] worker_thread+0x256/0x3a0 [50598.774818] ?
