Bug#124117: boot-floppies: udbootstrap exits after base install
I checked in some code to give a primitive register dump if a segmentation
fault happens in debugging mode. Maybe that will help find out where the
crash is happening. Anybody want to try it out?
You should see something like this on the screen when a segfault happens:
*** Segmentation fault
EAX: 00000000 EBX: 401ad1f0 ECX: bffff840 EDX: 00000000
EDI: bffffb94 ESI: 4001530c EBP: bffffb68 ESP: bffff9a4
EIP: 0805521a EFLAGS: 00210296
Trap: 0000000e Code: 00000006
*** Press RETURN to continue
The EIP number is the most important one, being the address of the instruction
that caused the fault.
