4.16s: Assertion failure in ext3_flush_inode_reservation

Hi Marc,
hello list,

I am running WOLK 4.16s on an Intel Celeron. I have mounted some
filesystems with the "acl" option. Unfortunately, whenever I change to
a directory where I'm only granted access due to the ACLs on this
directory, create a single directory there (which correctly inherits
the default ACLs from its parent directory) and then "rmdir" this
directory, I get a:

demeter kernel: Assertion failure in ext3_flush_inode_reservation() at
inode.c:2447: "test_bit(EXT3_STATE_INODE_RESERVATION,
&EXT3_I(inode)->i_state)"

(sorry for the linebreaking)

The dump from the kernel BUG is:

I just did some quick tests: This does also happen if I delete the
"acl" stanza from /etc/fstab and do a "mount -o remount /export/home"
(where /export/home is just an example of a filesystem mounted with
the "acl" option). So, next step, I deactivated quota for
"/export/home" and tried again to delete the (still existing)
directory. Now it reads:

Honestly, I'm running out of ideas right now. Can you help me?

To help you debug this problem, I have created a tarball containig the
following information:

-output from lspci and lspci -vvv
-the files /proc/interrupts and /proc/slabinfo
-the running kernel-config (in file dot.config)
-a file describing the policy of the quota and lvm10 packages
-versioning information about the gcc used to compile the kernel
-some other stuff which is quite self explanatory



Ciao,
Stefan
