Ok, but the one failing was the one from David Gaya, a POWER5 IBM iSeries (i5)
model 9406-520. Any idea why this one failed ? The log is :

The console I use is a HyperVisor Console (hvc), not serial.

  ppc64_caches.icache_line_size = 0x80
  htab_address                  = 0x0000000000000000
  htab_hash_mask                = 0x1ffff

And here stops with a system panel message "OS panic, Attemp"

So, it is indeed the hypervisore console at fault here. Cajus, do you have any
experience with the hypervisor console ?
