I introduced this bug in commit 05751d3f (vscsi: always use get_sense,
2011-08-03) because at the time there was no way to expose a sense
condition to SLOF and Linux manages to work around the bug.  However,
the bug becomes evident now that SCSI devices also report unit
attention on reset.

SLOF also has problems dealing with unit attention conditions, so
it still will not boot even with this fix (just like OpenBIOS).
IBM folks are aware of their part of the bug. :-)
