Server hung due to Intel network card bug in latest kernel:

Had to perform a cold start on the server and change kernel. Server is now stable however mysql will not start:

from the error.log (attached)

InnoDB: Last MySQL binlog file position 0 1102629, file name master-bin.001789
InnoDB: Cleaning up trx with id 13330155401

InnoDB: Failing assertion: trx->update_undo == NULL
InnoDB: We intentionally generate a memory trap.

Server cannot recover.

How to repeat:
Shutdown MySQL dirty - cold stop.

Suggested fix:
Not known.

We modified my.cnf 'skip-slave-start = 1'.

Had to do "innodb-force-recovery = 4" to get the server to start.

According to the documentation: "Values of 4 or greater can permanently corrupt data files." Therefore, we are considering the server as lost and we will rebuild from another master (we are using GTID).

Thank you for the report, I'm not able to reproduce this issue at my end on any of the 5.5,5.6,5.7 and 8.0 latest GA build.
If you can provide more information, feel free to add it to this bug and change the status back to 'Open'.

Thank you for your interest in MySQL.
