Hi all!
I've PCM 3643, 8 port dumb multiport serial card from Advantech.
This card works nice with 2.6.12 but with 2.6.13.4 I can see only two
ports!
This is dumb 8250 (exactly: 16550A) multiport board. In 2.6.12 I've the
following settings:
CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_NR_UARTS=4
CONFIG_SERIAL_8250_EXTENDED=y
CONFIG_SERIAL_8250_MANY_PORTS=y
CONFIG_SERIAL_8250_SHARE_IRQ=y
CONFIG_SERIAL_8250_MULTIPORT=y
CONFIG_SERIAL_8250_RSA=y
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
I've tried to setup same in 2.6.13.4, but it claims:
.config:761: trying to assign nonexistent symbol SERIAL_8250_MULTIPORT
I suspect that this is the problematic setting but there is nothing
about this in any Changelog.
What should I do ?
Jarek.

Please send the kernel messages from this kernel so we can see what's
going on. (this would be useful whatever.)
At a guess you need to increase CONFIG_SERIAL_8250_NR_UARTS. It now
represents the _total_ number of ports.
