Well 8250_pci.c mentions IT8871, so it is probably 8250 style in interface then. > I've got two questions on this: Is there a driver I should try force > loading on it (and if so, what options to use)? and is there any useful > testing I can do to report back to the LKML on this card? How many serial ports is your kernel configured to use? CONFIG_SERIAL_8250_NR_UARTS=16 CONFIG_SERIAL_8250_RUNTIME_UARTS=4 That is from my Debian system's kernel, and it won't activate more than 4 ports automatically. It will allow up to 16 to be activated though. I don't remember what the boot command is to override those values to make the system look for more ports. -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
