problems after installation of newest kernel
 

I compiled and installed the newest kernel source 2.6.16 on ubuntu 5.10 of my T43p laptop. But there are two problems afterwards. I can't automatically mount usb disks and always get the error message:
Error: device /dev/sdb1 is already mounted to /media/REMOVABLE1
Error: could not execute pmount

Another problem is I can't mount my cdrom as well. The error message is:

mount: special device /dev/scd0 does not exist

But all these things were fine before I installed the new kernel.
Anybody here can help me with this problem? Thank you very much in advance.

Here is my lspci result:

Did you check if /dev/sdb1 is really mounted on /media/REMOVABLE1 ? As you compiled a custom kernel 2.6.16, kernel automounter and subfs might have automatically mounted the filesysems on /media/<mnt-point>. What is the mount point you specified in /etc/fstab ?

Are you trying to say that YOU are trying to mount the device yourslef by running "mount /<mnt-directory>/<mnt-point>" or something similar ?

Here is my /etc/fstab file content:

proc /proc proc defaults 0 0
/dev/sda8 / ext3 defaults,errors=remount-ro 0 1
/dev/sda10 /home ext3 defaults 0 2
/dev/sda1 /media/sda1 ntfs nls=utf8,umask=0222 0 0
/dev/sda5 /media/sda5 ntfs nls=utf8,umask=0222 0 0
/dev/sda6 /media/sda6 ntfs nls=utf8,umask=0222 0 0
/dev/sda9 /usr ext3 defaults 0 2
/dev/sda7 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
#/dev/sdb1 /media/REMOVABLE1 vfat defaults 0 0
#/dev/sdb2 /media/REMOVABLE2 ntfs nls=utf8,umask=0222 0 0

I commented the last two lines because the usb disks automatically are mounted and appear on the desktop using default 2.6.12.9 kernel on ubuntu.

I am not sure that /dev/sdb1 is really mounted, how to check that? I am not trying to mount the device myself manually by the command. Hope this information is useful.

Thanks! :-)
