[Geekos-devel] Immediate assertion failures in project 1

Hello,
Moving from project0 to project1 I'm having immediate problems. Here's
the output of my bochs tests. Note that this is the output with JUST
project1 code, I didn't modify it at all.
8192KB memory detected, 1669 pages in freelist, 1048576 bytes in kernel heap
Initializing IDT...
Initializing timer...
Delay loop: 1824 iterations per tick
Initializing keyboard...
Initializing DMA Controller...
Initializing floppy controller...
fd0: cyl=80, heads=2, sectors=18
Initializing IDE controller...
Bad magic number (0) for PFAT filesystem
Failed to mount /a filesystem
Welcome to GeekOS!
Starting the Spawner thread...
Read_Fully failed to read /c/a.exe from disk
Failed assertion in brel: buf != ((void *)0) at ../src/geekos/bget.c,
line 836,
RA=1360b, thread=0x0000a000
Below is the full bochs.out file, if anyone needs it.
Any ideas?
Thanks,
Josh
