This looks like VFS have exploded for whatever reson, I think
because one ot these checks failed:
linux/fs/buffer.c:
if (size & (get_hardsect_size(to_kdev_t(bdev->bd_dev))-1))
BUG();
/* Size must be within 512 bytes and PAGE_SIZE */
if (size < 512 || size > PAGE_SIZE)
BUG();
Can any of sparc64 people comment on what kind of exception will one
get for __builtin_trap?
Second BUG() seems to be out of the question, though.
Do you have CONFIG_DEBUG_BUGVERBOSE enabled?
Bye,
Oleg
