After updating to r624, I get the following:
0 > boot cdrom
[sparc64] Booting file 'cdrom' with parameters ''
Not a bootable ELF image
Not a Linux kernel image
Not a bootable a.out image
Loading FCode image...
Loaded 7120 bytes
entry point is 0x4000
Unhandled Exception 0x9000280200000000
PC = 0x00000000ffd0f05c NPC = 0x00000000ffd0f060
When I use gdb to trace down the source of the exception, it looks like this:
(gdb) l *0x00000000ffd0f05c
0xffd0f05c is in enterforth (../kernel/internal.c:71).
66 #define dbg_internal_printk( a... ) printk( a )
70 static inline void processxt(ucell xt)
72 void (*tokenp) (void);
74 dbg_interp_printk("processxt: pc=%x, xt=%x\n", PC, xt);
75 tokenp = words[xt];
