This review is from: StarTech 8 Port Native PCI Express RS232 Serial Adapter Card with 16950 UART Model PEX8S952
Pros: Worked with Debian Lenny. It is necessary to append "8250.nr_uarts=10" (without quotes) to the Linux kernel command line (e.g., in /boot/grub/menu.lst or in /etc/default/grub) so that the kernel expects a high enough number of serial ports. 10 is chosen above assuming 2 built-in serial ports. I'm using mine in an HP ProLiant M110 G7.
Cons: In my system, the mapping from physical ports to /dev/ttyS* is as follows: Cable 1 - /dev/ttyS4 Cable 2 - /dev/ttyS5 Cable 3 - /dev/ttyS6 Cable 4 - /dev/ttyS7 Cable 5 - /dev/ttyS8 Cable 6 - /dev/ttyS9 Cable 7 - /dev/ttyS2 Cable 8 - /dev/ttyS3 ... not very intuitive.
Other Thoughts: I haven't had it in use long enough to comment on reliability.
