setserial的问题

应该是个BUG。

Aha!  So I'm not alone.  It appears there is a multilegged thing called a
bug in the present kernel.  Let me make a couple of observations re the
config for 2.6.18-1.2798.fc6xen.  I looked at it with a make xconfig,
thinking I might rebuild it, and found with grep:

[root coyote 2.6.18-1.2798.fc6-i586]# grep SER .config
CONFIG_SERIO=y
CONFIG_SERIO_I8042=y
CONFIG_SERIO_SERPORT=y
# CONFIG_SERIO_CT82C710 is not set
# CONFIG_SERIO_PARKBD is not set
# CONFIG_SERIO_PCIPS2 is not set
CONFIG_SERIO_LIBPS2=y
CONFIG_SERIO_RAW=m
CONFIG_SERIAL_NONSTANDARD=y
# CONFIG_ESPSERIAL is not set
CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_PCI=y
CONFIG_SERIAL_8250_PNP=y
CONFIG_SERIAL_8250_CS=m
CONFIG_SERIAL_8250_NR_UARTS=32 <--------WTH?
CONFIG_SERIAL_8250_RUNTIME_UARTS=4 <----WTH?
CONFIG_SERIAL_8250_EXTENDED=y
CONFIG_SERIAL_8250_MANY_PORTS=y
CONFIG_SERIAL_8250_SHARE_IRQ=y
CONFIG_SERIAL_8250_DETECT_IRQ=y
CONFIG_SERIAL_8250_RSA=y
# CONFIG_SERIAL_8250_FOURPORT is not set
# CONFIG_SERIAL_8250_ACCENT is not set
# CONFIG_SERIAL_8250_BOCA is not set
# CONFIG_SERIAL_8250_HUB6 is not set
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_SERIAL_JSM=m
# CONFIG_SND_SERIAL_U16550 is not set

Now, I snipped the USB stuff back out.  And, note that the 8250 is set for
32 of them, with 4 being the default.  My working kernel is 2 & 2 there.  
I think I need a beer, coffee isn't working anymore

Can we file a bug?
