Since you're mounted with "defaults", ACLs and user xattrs are disabled.
Both options need to be enabled explicitly. "Trusted" xattrs are enabled
by default, but they're root-only and I doubt they're in use.

The code path should go like so:
- - reiserfs_getxattr()
~  - reiserfs_xattr_read_lock()
~  - posix_acl_access_get()
~    - xattr_acl_get()
~      -- if !reiserfs_posixacl
~      -- return -EOPNOTSUPP
~  - reiserfs_xattr_read_unlock()

There's nothing in there that should be causing the behavior you're
seeing. However, I don't doubt that your session is hanging, so let's
try to figure out what's causing it.

What I'll need from you is a trace of the hung process. Enable alt+sysrq
(echo 1 > /proc/sys/kernel/sysrq), switch to a text console, and
generate a trace using alt+sysrq+t.

Next, decode the trace (dmesg | ksymoops), and email it to me. Hopefully
I'll be able to figure out what the problem is.

Thanks.
