Re: ISAPNP BUG: 2.4.65 ne2000 driver w. isapnp not working

[Michael Frank <mflt1@micrologica.com.hk>]

Original 2.5.65. Put some printks in.

Two tries with service network start. Success on the second try.

Here are the messages

First try
Mar 24 08:01:16 mhfl1 network: Setting network parameters:  succeeded
Mar 24 08:01:17 mhfl1 ifup: Cannot find device "eth0"
Mar 24 08:01:18 mhfl1 network: Bringing up loopback interface:  succeeded
Mar 24 08:01:19 mhfl1 kernel: ne: ne_probe
Mar 24 08:01:19 mhfl1 kernel: ne: ne_probe_isapnp

It seems that pnp does not work the first try:

Mar 24 08:01:19 mhfl1 kernel: pnp: res: The PnP device '01:01.00' is already active.

Mar 24 08:01:19 mhfl1 kernel: ne.c: You must supply "io=0xNNN" value(s) for ISA cards.
Mar 24 08:01:19 mhfl1 ifup: ne device eth0 does not seem to be present, delaying initialization.
Mar 24 08:01:19 mhfl1 network: Bringing up interface eth0:  failed

Second try
Mar 24 08:01:20 mhfl1 network: Setting network parameters:  succeeded
Mar 24 08:01:21 mhfl1 ifup: Cannot find device "eth0"
Mar 24 08:01:22 mhfl1 network: Bringing up loopback interface:  succeeded

ne_probe1 and ne_probe_isapnp have only a printk at their top

---------

int __init ne_probe(struct net_device *dev)
{
  unsigned int base_addr = dev->base_addr;

  printk("ne: ne_probe\n");
  SET_MODULE_OWNER(dev);

/* First check any supplied i/o locations. User knows best. <cough> */
  if (base_addr > 0x1ff)	/* Check a single specified location. */
    return ne_probe1(dev, base_addr);
  else if (base_addr != 0)	/* Don't probe at all. */
    return -ENXIO;

/* Then look for any installed ISAPnP clones */
  if (isapnp_present() == 0)
    printk("ne: no isapnp found\n");
  else if (ne_probe_isapnp(dev) == 0) {
    printk("ne: ne_probe_isapnp == 0\n");
    return 0;
  }

#ifndef MODULE
/* Last resort. The semi-risky ISA auto-probe. */
  for (base_addr = 0; netcard_portlist[base_addr] != 0; base_addr++) {
    int ioaddr = netcard_portlist[base_addr];
    if (ne_probe1(dev, ioaddr) == 0)
      return 0;
  }
#endif
  
  return -ENODEV;
}
