Hello,
After enabling RTEMS_DEBUG like you told me, I found the test I left running over the weekend like this

[/] # assertion "first != _Chain_Tail( &ready_queues[ index ] )" failed: file "../../cpukit/../../../stm32f7/lib/include/rtems/score/schedulerpriorityimpl.h", line 166, function: _Scheduler_priority_Ready_queue_first


This means that the scheduler tries to use the first thread of an empty ready queue. Someone corrupted the scheduler data structures. This could be a general scheduler bug, a heap corruption, a stack overflow, some arbitrary memory corruption.

Which RTEMS 4.11 release do you use exactly?
