i386 16MHz
>Description:
sio2 was configured for correct port and irq, but was not being
probed. Turned on flags 0x80 to find failing routine. Said probe
test 3 failed. Tried adjusting DELAY() values before failure[3]
to no avail.
>How-To-Repeat:
just reboot with internal modem with correct irq and port address set
(proper sio? enabled, of course), in 2.2.1 RELEASE.
>Fix:
in /sys/i386/isa/sio.c, apply this patch:
DELAY(10000); /* Some internal modems need this time */
if (idev->id_irq != 0)
- failures[3] = isa_irq_pending(idev) ? 0 : 1;
+ failures[3] = isa_irq_pending(idev) ? 1 : 0;
failures[4] = (inb(iobase + com_iir) & IIR_IMASK) - IIR_TXRDY;
Anyhow, this is what my sio.c said. In the above at '-', it is implying
that probe test 3 will fail if there is no irq pending, which is
the opposite of what we want.
