Hi Salvatore
A user in Debian reported the following kernel oops when running on 6.12.41 (but apparently as well on older versions, though there were several netfs related similar issues, so including Max Kellermann as well in the recipients)
Thanks for looking into this issue. 6.1 from bookworm did not crash since this morning.
Installed 6.16 from debian experimental - just the linux-image package.
Linux go 6.16-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.16.1-1~exp1 (2025-08-16) x86_64 GNU/Linux
Running cachefilesd, /home on NFS
25 minutes uptime. 6.12 would for have oopsed before. Mostly in the first 5 minutes.
I have upgraded several machines from Bookworm to Trixie - some make use of NFS but none as heavily as my office workstation with /home on NFS. All the other machines are either on ARM or INTEL metal or virtualised KVM machines. Not seen that issue on those other machines.
I suspect it could be a problem affecting only that specific CPU indeed hitting an invalid opcode.
vendor_id : AuthenticAMD cpu family : 25 model : 80 model name : AMD Ryzen 7 PRO 5750GE with Radeon Graphics stepping : 0 microcode : 0xa500011
