V4 - D32227_A1x incompatible motherboard
On the FUJI D32227_A1x motherboard the SPEC doesn't work most of the
time.
Slot x1 and x4 doesn't work at all: it freeze the system. Depending on
the driver:
- it freeze on FPGA configuration (fine-delay)
- it freeze after few minutes of usage (fine-delay with timer, BE-RF obs-box [no mezzanine])
- receive only one interrupts, after a while (~30s) it freeze (BE-RF obs-box [no mezzanine])
On slot x16 it works most of the time, but it's not 100% reliable
It's impossible to get error messages from the kernel because the system is completely frozen. It happened only a single time that it prints messages about: hardware error, Process context corrupter, CPU synchronization failure
