This happened while trying to dump the UEFI BIOS off of a T2SEEP rev2 Motherboard with an EPYC GENOA 9654QS on proxmox.
Original Shell output:
flashrom -p internal -r /root/output.rom flashrom unknown on Linux 6.8.12-2-pve (x86_64) flashrom is free software, get the source code at https://flashrom.org
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found chipset "AMD FP4". Enabling flash write... FCH device found but SMBus revision 0x71 does not match known values. Please report this to flashrom@flashrom.org and include this log and the output of lspci -nnvx, thanks!. Could not determine chipset generation.PROBLEMS, continuing anyway No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically.
Due to the high number of cores of the associated CPU, please find the output of the lspci -nnvx attached as a .txt file
Kind Regards and thank you for developing FOSS software
