When I conect my external HD I get this message:

| umass0: Cypress Semiconductor USB2.0 Storage Device, rev 2.00/0.01, addr 2
| umass0: Get Max Lun not supported (STALLED)
| da0 at umass-sim0 bus 0 target 0 lun 0
| da0: <ST320082 2A \\0000\\0000> Fixed Direct Access SCSI-0 device

| da0: 190782MB (390721968 512 byte sectors: 255H 63S/T 24321C)

And if I boot my computer with it connected I get the following error:

| Fatal trap 12: page fault while in kernel
| fault virtual address	= 0x21
| fault code		= Supervisor read, page not present
| instruction pointer	= 0x8:0xc044f50c

| current process		= 36 (swi5: clock sio)
| trap number		= 12
| panic: page fault
| Uptime: 14s

I have compiled my kernel (5.3-STABLE) with device EHCI in order to be
able to transfer files as faster as posible.

The external hd propierties:
2 partitions of 90GB, and both are fat32 formatted, I need it to share
information with windows.


Can I do something to be able to boot my computer with the hd connected?
