There is at probably least one more thread involved that has the
semaphore and is deadlocked. One way to look for this is to use screen
to capture all the output of the "bta" command in kdb (use LINES=10000
to keep from having to page the output) and look for 0xc6bd5af4 which is
the address of the dentry involved. You may also have to look for the
inode address inode address, which you'd have to pull out of the dentry.
