I'm seeing problem on an HP 15-da1009cy laptop. I've tried both the Ubuntu package rtl8821ce-dkms version 5.5.2.1-0ubuntu4~20.04.2 and the code from https://github.com/tomaspinho/rtl8821ce. Both result in a module that crashes intermittently. Crashes result in following log entries: [FSep 3 12:05:27 TheDude wpa_supplicant[699]: wlo1: Trying to associate with 4c:01:43:71:b6:18 (SSID='The Pipeline' freq=5200 MHz) Sep 3 12:05:27 TheDude kernel: [ 2200.706812] ------------[ cut here ]------------ Sep 3 12:05:27 TheDude kernel: [ 2200.706937] WARNING: CPU: 6 PID: 813 at /var/lib/dkms/rtl8821ce/5.5.2.1/build/core/rtw_rf.c:215 rtw_get_scch_by_cch_offset+0x54/0x92 [rtl8821ce] Sep 3 12:05:27 TheDude kernel: [ 2200.706939] Modules linked in: rpcsec_gss_krb5 auth_rpcgss nfsv4 nfs lockd grace fscache snd_sof_pci snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda snd_sof_intel_byt snd_sof_intel_ipc snd_sof snd_sof_xtensa_dsp snd_hda_ext_core snd_soc_acpi_intel_match snd_soc_acpi snd_soc_core snd_compress ac97_bus snd_pcm_dmaengine snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_intel mei_hdcp snd_intel_dspcfg snd_hda_codec snd_hda_core snd_hwdep intel_rapl_msr snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel snd_seq uvcvideo videobuf2_vmalloc kvm videobuf2_memops snd_seq_device rapl videobuf2_v4l2 rndis_host videobuf2_common rtl8821ce(OE) nls_iso8859_1 intel_cstate cdc_ether joydev snd_timer videodev input_leds usbnet mc hp_wmi serio_raw wmi_bmof mii intel_wmi_thunderbolt sparse_keymap snd hid_multitouch mei_me cfg80211 processor_thermal_device soundcore mei intel_rapl_common intel_soc_dts_iosf Sep 3 12:05:27 TheDude kernel: [ 2200.707003] intel_pch_thermal int3403_thermal int340x_thermal_zone int3400_thermal hp_wireless acpi_thermal_rel mac_hid acpi_tad acpi_pad sch_fq_codel parport_pc ppdev lp parport sunrpc ip_tables x_tables autofs4 btrfs xor zstd_compress raid6_pq libcrc32c dm_mirror dm_region_hash dm_log hid_generic usbhid hid i915 crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel i2c_algo_bit crypto_simd drm_kms_helper nvme syscopyarea sysfillrect cryptd sysimgblt psmouse glue_helper fb_sys_fops drm nvme_core r8169 i2c_i801 ahci realtek libahci wmi video Sep 3 12:05:27 TheDude kernel: [ 2200.707060] CPU: 6 PID: 813 Comm: RTW_CMD_THREAD Tainted: G W OE 5.4.0-45-generic #49-Ubuntu Sep 3 12:05:27 TheDude kernel: [ 2200.707063] Hardware name: HP HP Laptop 15-da1xxx/8532, BIOS F.23 11/29/2019 Sep 3 12:05:27 TheDude kernel: [ 2200.707163] RIP: 0010:rtw_get_scch_by_cch_offset+0x54/0x92 [rtl8821ce] Sep 3 12:05:27 TheDude kernel: [ 2200.707169] Code: 71 77 06 40 80 fe 03 74 35 8d 47 d6 3c 81 77 06 40 80 fe 02 74 36 8d 47 da 3c 89 77 04 84 c9 75 39 0f 0b b8 00 00 00 00 5d c3 <0f> 0b 89 d0 eb f8 8d 47 02 83 ef 02 80 fa 02 0f 45 c7 eb ea 8d 47 Sep 3 12:05:27 TheDude kernel: [ 2200.707172] RSP: 0018:ffffbb63809dfdb8 EFLAGS: 00010246 Sep 3 12:05:27 TheDude kernel: [ 2200.707176] RAX: 0000000000000026 RBX: ffffbb638050c000 RCX: 0000000000000000 Sep 3 12:05:27 TheDude kernel: [ 2200.707178] RDX: 0000000000000000 RSI: 0000000000000001 RDI: 0000000000000026 Sep 3 12:05:27 TheDude kernel: [ 2200.707181] RBP: ffffbb63809dfdb8 R08: 0000000000000001 R09: 0000000000ffff0a Sep 3 12:05:27 TheDude kernel: [ 2200.707183] R10: 0000000000000000 R11: 00000000c0d1de2a R12: 0000000000000002 Sep 3 12:05:27 TheDude kernel: [ 2200.707186] R13: 0000000000000000 R14: ffffbb63808e1000 R15: 0000000000000026 Sep 3 12:05:27 TheDude kernel: [ 2200.707189] FS: 0000000000000000(0000) GS:ffff93d276380000(0000) knlGS:0000000000000000 Sep 3 12:05:27 TheDude kernel: [ 2200.707192] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Sep 3 12:05:27 TheDude kernel: [ 2200.707195] CR2: 0000026e083db000 CR3: 0000000269fda003 CR4: 00000000003606e0 Sep 3 12:05:27 TheDude kernel: [ 2200.707198] Call Trace: Sep 3 12:05:27 TheDude kernel: [ 2200.707337] rtw_hal_set_chnl_bw+0x116/0x11b [rtl8821ce] Sep 3 12:05:27 TheDude kernel: [ 2200.707427] set_channel_bwmode+0x9b/0xe4 [rtl8821ce] Sep 3 12:05:27 TheDude kernel: [ 2200.707513] join_cmd_hdl+0x2df/0x36f [rtl8821ce] Sep 3 12:05:27 TheDude kernel: [ 2200.707542] ?
