T440 Error PCI1318 A fatal error was detected on a component at bus 4 device 0 function 1.
I have a T440 with Proxmox Virtualization runnig on it since 7 years.
2x RAID1 runs on PERC H730P Adapter.
It normally works like a charme. But since months the error "PCI1318 A fatal error was detected on a component at bus 4 device 0 function 1." appears in the logs.
And sometimes the whole server stops working when rebooting. Then I have to stop and start via iDRAC.
All firmware is updated, Proxmox is v8 (updated). How can I diagnose if the RAID controller is faulty?

Hello thanks for choosing Dell and welcome to our community.
I'm not sure if we support Promox at this point.
Supported Operating Systems | Dell US
Will Dell ever support proxmox | DELL Technologies

The solution for me is found! It wasn´t the controller. The problem ist the Kerner >6.5 with the Broadcom network interface cards. The are not compatible. If you disable them in system Bios the machine ist booting fine (PVE9) without any error AND with the Perc H730p working. Check out the reddit thread: https://www.reddit.com/r/Proxmox/comments/1o6lrh2/server_not_rebooting_properly/
Now I put in another network card and everything is fine!
Hope this helps every DELL T440 User to give their server a new job
