In some cases the non-debug version can work with "mkfs.xfs", but it
could not in most case.
I tried to disable most services in the system, but it seems have no
related to the system load.
So I suppose it is easy to reproduce problem. Please show 'dmesg' output
for the hung case when debug is turned off. Did you see register dump
message when that happened? Please also try attached patch and show the
hung dmesg (with tured off heavy debug).
There is no message when my system hung with debug disabled.
After I patched your new code, there is no hang anymore. I got following
message:
