I have the same effect on v240. Booting from network works like a charm,
but booting from SILO stops after "Remapping the kernel... done". I'm
using kernel 2.4.26smp.
I reported this problem here more than a year ago:

The problem is that the people who can work on fixing
this problem (whether it is in the kernel or SILO,
we still don't know) are not able to reproduce it.

Using PROM built-in option: boot net:dhcp.

The problem lies in SILO, we're using 1.2.6 in our (gentoo) v240 just
fine to boot off disk.
No kernel is rock-solid stable on the v240, though 2.4 lasts longer.
I'm guessing it has to do with IIIi SMP since we get tons of "CPU[1]:
Cheetah+ D-cache parity error at TPC[00000000005d3328]" (with varying
CPU number and addresses) before one of the processors goes offline/gets
stuck at which point it's time to reboot.

Known SMP bug with UltraSPARC-IIIi processors. They can randomly hang
during an L2 cache transaction, and the only way to get them unstuck
is to gain ownership of an L2 cache line (from the other cpu which is
still alive) that stuck processor holds.
I'm not willing to work on a workaround for this chip errata until
I have physical access to an SMP UltraSPARC-IIIi system for several
weeks.

The fact that an older version of SILO works does not actually mean the
problem is in SILO. SILO writes to memory, kernel reads from that
memory. Either part can be buggy, and both have in the past.
If people want this fixed, they need to get a box that's breaking in
front of one of those of us who can debug this sort of failure or debug
it themselves.
