Bug 64881 – neither hotplug-20040920 nor coldplug create eth0 for my nic

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matteo Settenvini 2004-09-21 12:12:29 UTC]

I use a Broadcom ethernet card fully supported by the tg3 module.
With hotplug 20040401, everything runs ok.

with 20040920, /dev/eth0 isn't created, nor the module automatically loaded. 
Manually modprobing tg3 reports in dmesg (as it should be):

eth0: Tigon3 [partno(BCM95901A50) rev 3001 PHY(5705)] (PCI:33MHz:32-bit) 10/100BaseT Ethernet 00:06:1b:c1:1a:f3
eth0: HostTXDS[1] RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0] WireSpeed[1] TSOcap[1]

but eth0 is still not created. Downgrading to 20040401 makes it work again.

I forgot: using udev032

not related to tg3 module, same here with 8139too

Did you notice that the hotplug startup script no longer autoloads modules?
It said so when you merged the 20040920 release.

You need to emerge the coldplug package for this to work the same way it used to.

[Comment 4 Matteo Settenvini 2004-09-22 09:12:59 UTC]

I reopen this bug since I tried with coldplug and it didn't work. (I added coldplug to the boot level, as hotplug)

The eth0 is correctly modprobed with coldplug (with hotplug it wasn't, I had to do insmod it manually and eth0 didn't appear in /dev/ anyway), but the device is still not created. I had to revert to hotplug-20040401 anyway.

PS: I also obtain a *huge* list of errors when hotplug/coldplug try to load the isapnp devices... is this "normal"? The only solution is to rm /etc/hotplug/isapnp.rc...

[Comment 5 Greg Kroah-Hartman (RETIRED) 2004-09-23 11:37:12 UTC]

The pnp bug is now fixed upstream and will be fixed in the next release.

The coldplug issue doesn't seem to be a hotplug/coldplug issue, as if the 
device is loaded properly, that's all that it does.
