I am having similar issues and the last thing I am going to try is to remove my SSD which is a Seagate Ironwolf NVMe in a PCIe adaptor. I have replaced all the RAM, the 10GbE NIC back to 1GbE and as well as the usb drive for the OS and other tests.
Has it stabilised for you? I am also running 6.10.rc2 and I am still having the kernal panic.
