Well, there are too many bugs with the previous driver, so unless
someone with a 274x can figure it out ;-)
Doug Ledford found one bug that may be causing problems. It is in
aic7xxx_register where we do this:
for (i = 0; i <= NUMBER(p->device_status); i++)
{
p->device_status[i].commands_sent = 0;
p->device_status[i].flags = 0;
p->device_status[i].active_cmds = 0;
p->device_status[i].last_reset = 0;
}
Change the first line to this:
for (i = 0; i < NUMBER(p->device_status); i++)
It's on or abouts like 5011 in aic7xxx.c.
