Hi,
According to my injected debugging message, the first time
"inb(scp->altioaddr)" was executed in ata_intr(), it returns 0xd0(busy):
/* if drive is busy it didn't interrupt */
if (inb(scp->altioaddr) & ATA_S_BUSY)
return;
The booting message then said: "ata0-master: ata_comand: timeout
waiting for intr," and stopped to interact with my hard disk attached on
ata0-master anymore. However, if I forced an interrupt clear before busy
return, the timeout condition can be resolved & all further disk I/O
operations went normally:
/* if drive is busy it didn't interrupt */
if (inb(scp->altioaddr) & ATA_S_BUSY)
{
/* clear interrupt */
inb(scp->ioaddr + ATA_STATUS);
return;
}
Include the above hacks, there are two other temporary "fixes"
against ata-all.c, 1.50.2.14. All of them work in my 4.2-R box. The first
is to replace the status checking routine in ata_intr() with the old one
(in 1.50.2.7):

I'm not sure whether any of the above hacks breaks anything or
just doesn't make sense(just for my kludge laptop?); therefore, would
someone please test/review the above patches for me?
