Public bug reported:
Description: Encountered multiple issues while attempting to connect and
activate a Thunderbolt device. Initially, the device was recognized but
then disconnected shortly after. System logs indicated a DROM data CRC
mismatch, despite which, the system attempted to continue with the
device activation. Subsequent log entries indicated failure in the
device activation path, as well as a failed attempt to activate the PCIe
tunnel, leading to an abort.
Something may be useful: boltctl command can not find this eGPU.
Error Messages:
Device disconnected.
DROM data CRC32 mismatch (expected vs. actual value discrepancy).
New device recognized but subsequent activation path failure.
PCIe tunnel activation failure and aborted attempt.
Kernel warning pointing to the tb_path_activate function.
System and Hardware Information
Operating system version, kernel version (6.5.0-21-generic).
Attempted Resolution Steps:
Reconnecting the Thunderbolt device.
Checking and updating the system kernel and firmware.
Adjusting Thunderbolt-related settings in BIOS/UEFI setup.
Expected Outcome:
Expected the Thunderbolt device to connect successfully and be stably
recognized by the system without encountering issues like DROM data mismatch or
activation path failures.
Actual Outcome
Faced a series of issues including frequent device disconnections, DROM data
checksum mismatches, activation path failures, and failed attempts to activate
the PCIe tunnel.
Additional Information
Provide all relevant system log entries and outputs.
Detailed information on any other attempted solutions or relevant setting
adjustments should also be included.
