Trap E in Kernel

[dryeo]

With 3.21.04 the system comes up but within a few minutes I get this trap, (extracted from dump with DumpTrapScreen?.cmd)

Exception in module: OS2KRNL

Internal revision 14.105_SMP

Changing various things in the BIOS including disabling the com port has no affect. Most previous versions the system hung hard after running a few minutes depending what was running. Thunderbird in particular seemed to trigger the problem when indexing messages I believe.
Version 3.19.14 is stable with workaround for com port issue (bug #528)

Which COM port driver are you using?
