This appears to be the case referenced by the "something" part of /* two possibilities: 0x30ps encodes number of parallel and * serial ports, or 0x1000 indicates *something*. This is not * immediately obvious, since the 2s1p+4s configuration seems * to offer all functionality on functions 0..2, while still * advertising the same function 3 as the 4s+2s1p config. */ in 8250_pci.c… You have two serial ports each on the 0xa000 0x3002 subsystems seen in lspci output, and then presumably the remaining two on the mystery 0xa000 0x1000. It's been 8 years since I scraped that information from documentation and experiments, and all I had at hand was a card with 2 serial ports and a parallel port (that I couldn't even test and that proved problematic since then), so I'm afraid I cannot be of more help here. I could hunt around and see if I still have the reference material somewhere if that'd be any help. Regards, Nicos
