Hi all, Is it expected that removing a usb serial adapter while you have a connection (eg tip) using it will panic a -stable system? I know it is expected if you remove a mounted umass device so wanted to see if its known behavior for serial before I file a pr. (adapter is <FTDI usb serial converter, class 0/0, rev 1.10/4.00, addr 3>) -stable version as of the 25th march, (may have existed before but the first time I forgot to close tip before removing the device was on this version.) cheer, Vince

So, yes, I would expect this behaviour based on the track record. Should it happen? The answer is no. File a PR? Also, I'd like to know what USB serial adapter you're using (brand, model, and a website of it if possible), for unrelated reasons.

There are two supported stable branch now. -------------- next part -------------- A non-text attachment was scrubbed...
