Hi,

I couldnt find any blkbk module in my dom0 (used modprobe -l). Do i
need to configure the module using menuconfig?
Tried using an initial ramdisk also but the error still occurs.

I was wondering if the error could occur due to mounting and then
unmounting of FC4 image?

Thanks,
Adit

Did you insmod blkbk?
And if you use FC4, you may need to use initrd.
