No, there was nothing unusual in the log files. I have no access to
the test machine at the moment, but there is a message when the
recovery starts, and a few seconds later the message "sync done".

It fails every time. This test was on an dual PIII 450 system, but it
also fails on a VIA C6 system with the 2.6.0-test5 kernel. Both
kernels are compiled without CONFIG_PREEMPT, because I had other
problems that might be related to this option:

Could this be related to CONFIG_DM_IOCTL_V4? I was not sure about this
option, and have not enabled it. Otherwise, I think it is time to put
in some printk's. Do you have suggestions where to start looking?
