| Description |
|
We saw a Sequoia client soft lockup during filesystem mount time. The backtraces from the console are in the sequoia_ion_console.txt attachment. No further info to go on at this time. Admins rebooted node before we got to investigate. |

Any ideas Alex? |

It is happening again, which many Sequoia client nodes hanging. This is a major problem for sequoia. The soft lockup messages are exactly the same, and the node is completely unresponsive. |

I am not aware of any. This is probably lower priority at the moment than other tickets. |
