Works on erc32 and psim
Fails on jmr3904 and xilinx_zynq_a9_qemu

The two failures are difference. On the MIPS, the issue is that _ISR_Get_level() is not returning the value that was set immediately above. I am guessing that the _ISR_Set_level() for the mips and arm ports translates the requested level into a register setting and then doesn't reverse the translation on the _ISR_Get_level().

The code in question is around line 130 with a printf() added to show the value:

ISR_Level current = 0;
ISR_Level last_proper_level;

_ISR_Set_level( current );
printf( "_ISR_Get_Level()=0x%08x current=0x%08x\n",

_ISR_Get_level(), current );

rtems_test_assert( _ISR_Get_level() == current );

jmr3904 output

BEGIN OF TEST SP 37 *
_ISR_Get_Level()=0x0000007f current=0x00000000
../../../../../../../rtems/c/src/../../testsuites/sptests/sp37/init.c: 133 _ISR_Get_level() == current

On the ARM, it is failing calling the body version of rtems_interrupt_disable() in rtems/src/intr.c. No obvious failure looking at the code.
