Ramdisk Bug?

Hi all

Having a few problems with 2.0.8 as a result of trying to rebuild a rescue
disk using yard-1.5. The ramdisk driver doesn't seem to work correctly.
The last time I did this was with 1.3.80 or so - no problems then. I have
a 32Mb pentium system. I built the kernel with the ramdisk and initial ramdisk
options enabled. The ramdisk devices /dev/ram[0-7] and /dev/initrd are correct.

After running into problems with yard I turned to ramdisk.txt in linux/
Documentation and attempted to create a ramdisk:
dd if=/dev/zero of=/dev/ram1 bs=1k count=2048
This terminates ok, but produces log messages such as
kernel: ctor 346
kernel: equest: I/O error, dev 01:01, sector 1302
kernel: equest: I/O error, dev 01:01, sector 2590
Then trying
mke2fs -vm0 /dev/ram1 2048
I seem to be able to build a file system on it (though in cycling through
this bug search I've had user error messages here sometimes).
mount -t ext2 /dev/ram1 /mnt
fails with the user error message
mount: wrong fs type or bad superblock on /dev/ram1.
Same result with different ramdisk devices and sizes.

Is this a bug or do I have a configuration problem?
