Note that the cachefiles dumps a load of info immediately prior to this BUG() which should be included in the description. Can you also try the four patches at the top of this branch from Kiran Kumar Modukuri? https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=fscache-fixes The topmost patch removes the BUG() and lets it fall through to the wait. The "Fix missing clear of the CACHEFILES_OBJECT_ACTIVE flag" patch fixes one of the causes of the BUG. David
