I don't have that board sorry but I guess out of bounds memory write happens causing boa= rd panic and then BSD host panic. This is interesting to verify BSD msdosfs / = fs driver cannot be manipulated by forged FAT device. One more question - just to eliminate some "background writes" - no problem occurred in terminal with no Xorg or you were working on the Xorg desktop? --=20 You are receiving this mail because: You are the assignee for the bug.=
