Comment 1 for bug 268430

Hi Glave,

I've got a few questions here for you. The 8250 and 8250_pnp modules actually correspond to the following kernel config options:

8250 => CONFIG_SERIAL_8250
8250_pnp => CONFIG_SERIAL_8250_PNP

However, in your description of navigating the kernel config menu you point to enabling CONFIG_SERIAL_8250 but then CONFIG_SERIAL_8250_CS (8250/16550 PCMCIA device support) instead of CONFIG_SERIAL_8250_PNP.

But regardless of which config option you really want, I can see that all three of these are being built for Hardy:

ogasawara@yoji:~/ubuntu-hardy/debian/config$ grep -rn "CONFIG_SERIAL_8250=" *
amd64/config:2337:CONFIG_SERIAL_8250=y
hppa/config:1104:CONFIG_SERIAL_8250=y
i386/config:1060:CONFIG_SERIAL_8250=y
ia64/config:2014:CONFIG_SERIAL_8250=y
powerpc/config:2016:CONFIG_SERIAL_8250=m
ogasawara@yoji:~/ubuntu-hardy/debian/config$ grep -rn "CONFIG_SERIAL_8250_PNP=" *
amd64/config:2345:CONFIG_SERIAL_8250_PNP=y
i386/config:1067:CONFIG_SERIAL_8250_PNP=y
ia64/config:2021:CONFIG_SERIAL_8250_PNP=y
ogasawara@yoji:~/ubuntu-hardy/debian/config$ grep -rn "CONFIG_SERIAL_8250_CS=" *
amd64/config:2339:CONFIG_SERIAL_8250_CS=m
hppa/config:1106:CONFIG_SERIAL_8250_CS=m
i386/config.386:1513:CONFIG_SERIAL_8250_CS=m
i386/config.server:1512:CONFIG_SERIAL_8250_CS=m
i386/config.generic:1511:CONFIG_SERIAL_8250_CS=m
ia64/config:2016:CONFIG_SERIAL_8250_CS=m
powerpc/config:2017:CONFIG_SERIAL_8250_CS=m

I do see that CONFIG_SERIAL_8250 and CONFIG_SERIAL_8250_PNP are built into the kernel rather than as a module. Could you maybe attach your dmesg output to verify if these modules are indeed being loaded or not? Thanks.
