Hi, list I found some io memory information is lost from /dev/iomem and want to find out why. I have a 2.6.16 kernel running on a ARM board (Samsung S3C2410). From the kernel log, I see 16 8250 serial ports were detected, and each of thoese ports has a memory address:

You see, there is no serial8250 informations. Can anyone here please tell me how this can happen? Does it mean the serial8250 driver don't populate or register in the /proc/iomem?
Can you look at the o/p of /proc/ioports and see if the entry is present here. Regards, --Prabhakar Lad
