Description of problem:
kernel hang that we think is a bug with __getblk_slow().
This bug is causing the TCs to hang immediately, while /sbin/sfdisk
tries to read the geometry(trying to read block 0). "sfdisk" command
is not always failing, but at the time of running test cases, it is
causing the hang immediately.
The implementation of "__getblk_slow()" seems to be causing this.
This function has to return the "buffer_head" structure for the given
block. For this it is trying to get buffer_head by
calling "__find_get_block" and "grow_buffers()"
Version-Release number of selected component (if applicable):
