I’m fairly certain I’m running into this reported issue:

https://devel.rtems.org/ticket/2792

Is there any status change on this?  Is there a temporary workaround recovery procedure?  I’m tempted to give the conditional wait a timeout.

The actual ram disk driver is in a different location and didn't have a trace equivalent.  Is there another way to get a trace from ramdisk?
