41CL - Warp Core Conflict with Card Reader?

[twoweims]

My Current Setup:

4: -LIB#4 R50
5: -TIME 3A
6: -PRINTER-
7: -AMC"OS/X
8: -YFNX 4C
9: -PWREXT B3
A: -WARP CORE+
B: -HEPAX'4H
C: NO FAT
D: NO FAT
E: CARD RDR 1E (I leave this empty for the card reader)
F: NO ROM (The same failure occurs with Warp Core Plugged in here)

Everything works great until I plug in the card Reader.

Thanks for taking a look at this.

** Edit to add more information **

I took the CL to MEMORY LOST and started over loading modules from scratch... Same Result.
I replaced the Card reader 1E version with a 1G version and the problem disappears.
