 |
|
Some time ago (I'm not exactly sure when it happened since I didn't have time to debug it) my laptop stopped being able to connect to the usb and ethernet ports of my Dell WD19TB Thunderbolt Dock.
The same dock works perfectly fine with an ubuntu machine.
I'm running the distribution kernel: 6.10.8-gentoo-dist
Does someone have any idea if I might be missing some kernel configuration ?
This is what shows up in dmesg:
| Code: | [ 787.446815] usb 3-3: new high-speed USB device number 7 using xhci_hcd
[ 788.526589] thunderbolt 0-0:3.1: new retimer found, vendor=0x8087 device=0x15ee
[ 789.342415] thunderbolt 0-3: new device found, vendor=0xd4 device=0xb070
[ 789.342429] thunderbolt 0-3: Dell WD19TB Thunderbolt Dock

should be enabled:
| Code: |
grep CONFIG_USB4 /usr/src/linux/.config
CONFIG_USB4_NET=m
CONFIG_USB4=m
# CONFIG_USB4_DEBUGFS_WRITE is not set
# CONFIG_USB4_DMA_TEST is not set

since it works at Ubuntu, you can compare the modules on both sides, like
| Code: | lsmod
lspci -k
dmesg |

comparing the output of lsmod, these are the modules that are on the ubuntu machine but not on mine:
| Code: |
'usb_common', 'evdev', 'cryptd', 'intel_lpss', 'configfs', 'xhci_hcd', 'crc_t10dif', 'scsi_mod', 'jitterentropy_rng', 'rc_core', 'button', 't10_pi', 'nls_cp437', 'ext4', 'xhci_pci', 'scsi_common', 'nls_ascii', 'watchdog', 'intel_hid', 'snd_hrtimer', 'snd_seq_dummy', 'battery', 'ledtrig_audio', 'af_alg', 'ecdh_generic', 'drm', 'drbg', 'crct10dif_generic', 'hid_generic', 'acpi_tad', 'ac', 'jbd2', 'crct10dif_common', 'usbcore', 'aesni_intel', 'ecc', 'autofs4', 'algif_skcipher', 'intel_lpss_pci', 'usbhid', 'sha512_generic', 'parport_pc', 'loop', 'crypto_simd', 'crc16',
'crc64_rocksoft_generic', 'dm_crypt', 'snd_seq', 'msr', 'dm_mod', 'x_tables', 'hid', 'irqbypass', 'fan', 'crc32c_generic', 'ppdev', 'parport', 'qrtr', 'sd_mod', 'sparse_keymap', 'mbcache', 'asus_wmi', 'drm_kms_helper', 'ansi_cprng', 'crc64', 'ccm', 'crc64_rocksoft', 'algif_hash', 'snd_hda_codec_realtek', 'lp', 'ctr', 'efivarfs', 'efi_pstore', 'sg', 'platform_profile', 'ip_tables', 'roles', 'cmac'

not sure if any are related to this issue.
Will get the lspci output tomorrow. |
