 - GENERIC.UP kernel hangs on v445 (missing interrupt?)
 
 sun4v:
- - current status: The kernel boots and starts the init process (pid 1) 
-   which spawns /sbin/sh (pid 2). This is forked as a new /sbin/sh (pid 3)
-   which crashes, probably due to MMU DPROT issues.
-   Looks like the user process tries to write to the stack as part of a save
-   instruction since cansave is zero. This causes a DMMU PROT trap (0x6c) which
-   calls sun4v_tl0_dtsb_prot which calls sun4v_datatrap which calls TRAP_SETUP().
-   This macro has code that does a save instruction, again to the user stack,
-   which again causes a MMU DPROT trap...
+ - current status: The kernel boots and starts the init process. 
+   The following processes seem to crash on and on so more debugging to be done...

 - 64-bit kernel support
 - 32-bit kernel support
 - libkvm
