- 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
