(2.4.0-test1-ac7)
Howdy. Something is odd in serial.c. I found this oddity this morning
while running a machine thru the gammut.
Here's a snippet of dmesg output, I added the portion that prints the
"Inside serial..." value.
Serial driver version 5.01 (2000-05-29) with MANY_PORTS
SHARE_IRQ SERIAL_PCI ISA
PNP enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A
Entered probe_serial_pnp()
Inside serial_pnp_guess_board, 00000000 (OPTi Audio 16)
register_serial(): autoconfig failed
Inside serial_pnp_guess_board, c11390e0 (OPTi Audio 16)
Inside serial_pnp_guess_board, c11392c0 (OPTi Audio 16)
Inside serial_pnp_guess_board, c1139320 (OPTi Audio 16)
Leaving probe_serial_pnp() (probe finished)
Here's the relevant code with the ">" being lines I added, this is from
drivers/char/serial.c:4900:
static int _INLINE_ serial_pnp_guess_board(struct pci_dev
*dev,
struct pci_board *board)
{
struct isapnp_resources *res = (struct isapnp_resources
*)dev->sysdata;
struct isapnp_resources *resa;
> printk("Inside serial_pnp_guess_board, %08lx (%s)\n", res,
dev->bus->name);
>
if (!(check_name(dev->name) ||
check_name(dev->bus->name)) &&
!(check_compatible_id(dev)))
return 1;
> if (!res)
> return 0;
>
if (res->next)
return 1;
Wowsers. Looks like we need to squash a lil' bugger here. I'm sure my
patch isn't the true and correct way but I didn't have time to go
further on this ;)
More information is available if you wish it. The full dmesg boot
output is available at http://stuph.org/kbug.20000604.
