Subject: Re: updated list of problems I got after upgrading kernel to 2.6
Date: Wed, 20 Dec 2006 17:58:31 +0800
I know such message may be a bit noise to gurus on this list, but as a
newbie I constantly find searching other people's old post might help,
so I just write done solution to all problems I have solved, hoping it
can help the next newbie lurking on this list or coming to this list by
googling around.

     I. [solved] keyboard doesn't work: solved, need to adjust keymap
        (thank you for suggested this);
    II. [solved] not able to access /dev/hda, probably new kernel
        does not recognise on-board IDE controller. Related kernel
        parameter I configured are:
             I. CONFIG_SUN_PARTITION: y
            II. CONFIG_BLK_DEV_SIIMAGE: y
        ==> solution is to activate CONFIG_BLK_DEV_CMD64X kernel option

   III. [given up] parallel port stopped working, it behave
        like /dev/null (swallow all input to it, no error message,
        printer no response). /dev/lp0 is not mentioned in dmesg. I
        remember on 2.4 kernel I use "PC-style Parallel Port" and it
        works in ECP mode. Related kernel parameter I configured are:
             I. CONFIG_PARPORT: y
            II. CONFIG_PARPORT_PC: y
           III. CONFIG_PARPORT_PC_FIFO: y
            IV. CONFIG_PARPORT_1284: y
        ==> progress: after re-creating /dev/lp0 node it works a bit
better
            dmesg | head -n 4 > /dev/lp0 would print something out
            dmesg | head -n 40 > /dev/lp0 would hang the OS
            my plan: next step is to text various parameter of parport

    IV. [solved] USB Printer do not work. dmesg shows it detected
        USB Printer but no device appear in /dev/usb. Related Kernel
        Parameter:
             I. CONFIG_USB_PRINTER: y
        ==> solution is to run this command as root:
            # mknode /dev/usblp0 c 180 0
            and set cups to use /dev/usblp0 for printer

     V. [almost given up] all ALSA sound driver are enabled, dmesg
        said Sun CS4231 is detected and use irq 10. Try to play mp3 file
        using madplay, it hangs there after display song title, no sound
        output, kill -TERM and kill -KILL cannot remove the dead
        mplayer. Related kernel config:
             I. CONFIG_SND: y
            II. CONFIG_SND_SUN_CS4231: y
        ==> current progress: will try using different kernel following 
            suggestions on the list or try alsa-driver package
    VI. [no clue yet] serial port doesn't work. I need serial port in
        order to manage another headless server with this machine acting
        as dumb terminal (using minicom).
                dmesg shows no ttyS device. 'MAKEDEV update' can
                create /dev/ttyS0 and /dev/ttys1 but accessing these
                devices is not possible:
                        sappho zhangweiwu # cat /dev/ttyS1
                        cat: /dev/ttyS1: No such device or address
                I have enabled following options in kernel:
                        sappho linux # grep -i serial .config
                        # CONFIG_SERIAL_NONSTANDARD is not set
                        # Non-8250 serial port support
                        CONFIG_SERIAL_SUNCORE=y
                        CONFIG_SERIAL_SUNZILOG=y
                        CONFIG_SERIAL_SUNSU=y
                        CONFIG_SERIAL_SUNSAB=m
                        CONFIG_SERIAL_SUNHV=y
                        CONFIG_SERIAL_CORE=y
                        CONFIG_SERIAL_JSM=y
