How to troubleshoot hardware

[ArminF]

Afternoon,
well... i reinstalled OPNsense but it seems to drop a crash report every now and then.

Can you give me some tips on how to troubleshoot hardware on BSD?

fsck show me this
71464 files, 683570 used, 115473836 free (4716 frags, 14433640 blocks, 0.0% fragmentation)
** /dev/gpt/efifs (NO WRITE)
** Phase 1 - Read FAT and checking connectivity
** Phase 2 - Checking Directories
** Phase 3 - Checking for Lost Files
6 files, 254 MiB free (520804 clusters)
MARK FILE SYSTEM CLEAN? no

***** FILE SYSTEM IS LEFT MARKED AS DIRTY *****

Any way to check this deeper?
Memory to check?

thank you!

Testing hardware is no different running BSD than any other OS. First I'd test the memory. For that you need to boot into memtest86 independent of the installed OS:

If the memory proves to be good you swap individual components until the problem is solved 

The efifs should not pose a problem, though. It's just a FAT filesystem holding the boot loader and never changes after installation.
