Hi Sevan,

At the risk of stating the obvious:

> Illegal instruction
> pid 19 (ps), uid 0: exited on signal 4
> Illegal instruction

The userland processes launched by /etc/rc are getting a SIGILL but it
is not clear why.

Could you do some experiments on your end to narrow this down a bit more:

- Boot to single user and then execute a variety of commands to figure
out whether the problem happens randomly or does is follow a
particular executable (for e.g. execute "ps", "stty", "fsck", "find",
"ls" etc).

- Did this problem start happening only recently?

- If you have a different host system does it happen there too? If you
have a different virtual machine does it happen there as well?

best
Neel
