So sync was hanging because journal thread has been waiting for IO which
apparently never finished. This tends to be a driver bug but the kernel
assertion failure on umount looks more interesting. This message:

> Manualer} still in use (536870912) [unmount of ext3 sdd1]
Shows the filesystem you tried to umount had a dentry whose use count
(d_count) was 536870912 instead of 0. Since 536870912 is 0x20000000 this is
very likely caused by buggy memory doing a bit flip so I suggest running
memtest and replacing the faulty DIMM...
