In "AMD Bolton FCH Register Reference Guide" (51192), page 2-154, this register "Interrupt Line – RW – 32 bits - [PCI_Reg:3Ch]" is 0x12/0x11 while having booted the vendor binary and 0xff/0xff when having booted coreboot.
This is about hudson, not bolton.. Unfortunately its RRG/RPR/databook is not public :( http://support.amd.com/en-us/search/tech-docs#k=a85x
Could the erratic value cause SeaBIOS boot issues? See http://www.coreboot.org/pipermail/seabios/2014-June/008148.html and http://www.coreboot.org/pipermail/seabios/2014-June/008150.html
lspci -s 10.{0,1} -nnvvvxx output follows.
