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 Mit freundlichen Gr=C3=BCssen -Beno=C3=AEt Panizzon- --=20 I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
