Package: src:linux Version: 6.1.55-1 Severity: important X-Debbugs-Cc: jamescope...@gmail.com Dear Maintainer, Hi, I have experienced an issue where my client lost access to an NFS server for a period of around 15 minutes, then immediately following server recovery, I experienced a kernel oops on the client (details below). What made this more severe was the fact that nfs4_do_reclaim exited with irqs disabled, which is possibly what resulted in a number of "rcu_preempt self-detected stall on CPU" errors and a very unstable system, leaving me no choice but to hit the reset button.
