Package: openssh-server Version: 1:8.4p1-3 Severity: important X-Debbugs-Cc: jgmanilla@yahoo.com Dear Maintainer, After attempting to scp or rsync a directory with many large-ish files (20-600M) to a remote host, the remote machine will crash. This hasn't happened with smaller file transfers; only when the directory contains gigabytes of data, after about 3GB have been copied. I tried once to scp a similar ammount of data from a different client to the same machine, with the same result. The commands used were: scp -r ./localdirectory jgmanilla@remotehost:~/ rsync -avP ./localdirectory jgmanilla@remotehost:~/ If you happened to be logged into an ssh session, you may get the following message before the system goes down: Message from syslogd@localhost at Dec 12 16:22:24 ... kernel:[ 406.101940] Internal error: Oops: 96000004 [#1] SMP Message from syslogd@localhost at Dec 12 16:22:24 ... kernel:[ 406.130105] Code: b9402a62 f9405e63 8b020014 dac00e81 (f8626814) Expected outcome was for scp and rsync to complete their file transfers with no errors. The hardware of the remote machine was a RockPro64.

Also, are you using the on-board Ethernet or a separate adapter in the RockPro64? Ben. -- Ben Hutchings The two most common things in the universe are hydrogen and stupidity.

Please advise. You'll need to capture the kernel log using a serial console <https://www.kernel.org/doc/html/latest/admin-guide/serial-console.html> or netconsole <https://www.kernel.org/doc/html/latest/networking/netconsole.html>.
