this is an excellent bug report. it's interesting that the
actual irq is 11, but the panic is for exception/interrupt 14.
are you sure the port (0xd4544400) is accurate? generally, bios
aligns bars a bit more.
if you can pxeboot this machine, would you be willing to try
/n/sources/contrib/quanstro/9pxeload9?
also, if you have a machine to compile on, if you could add
a debug to this loop from the 9load on sources:
/n/sources/plan9/sys/src/boot/pc/sdiahci.c:1584,1588
for(i = 0; i < n; i++)
if(ahciidle(c->drive[i]->port) == -1){
dprint("intel 63[12]xesb: port %d wedged;
abort\n", i);
goto loop;
}
=>
for(i = 0; i < n; i++){
print("idle ahci %d\n", n);
if(ahciidle(c->drive[i]->port) == -1){
dprint("intel 63[12]xesb: port %d wedged;
abort\n", i);
goto loop;
}
}
