Bug 2029 – eepro100 driver in 2.4.19r1 broken

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Gerald Combs 2002-04-23 08:44:21 UTC]

After installing Gentoo on my HP Omnibook xe3, I had major problems using the 
built-in EtherExpress Pro 100 interface.  When running at 10 Mbps half duplex, 
the driver would lock up after a few seconds of network activity.  
A "wait_for_cmd_timeout" error would be logged to dmesg when this happened.  
Shutting down the interface and bringing it back up fixed things briefly.

There were no problems running at 100 Mbps full duplex.  I didn't get a chance 
to test other duplex/speed modes.  

I tried using the eepro100 drivers from the 2.4.18 and 2.4.19-pre7 source 
trees. The 2.4.18 version works fine at both 10 and 100 Mbps.  2.4.19-pre7 had 
the same lockups at 10 Mbps.

You may want to try gentoo-sources-2.4.19 (note gentoo-sources, not
linux-sources).  This is a 2.4.19-pre7-ac2 kernel, so we can see if Alan Cox
fixed it.  Sounds like Marcelo should be informed of this.  I"ll send him an email.

[Comment 2 Daniel Robbins (RETIRED) 2002-04-25 01:27:52 UTC]

I sent an email to Marcelo about this.  I need to follow-up.

After installing and building from gentoo-sources-2.4.19 I still have the same
problem.  If I generate a significant amount of traffic, e.g. by running "emerge
rsync" while connected at 10 Mbps half duplex, the connection hangs and dmesg
displays several lines of

eepro100: wait_for_cmd_done timeout!

I can do more testing if needed.

I got the same on my Omnibook 6100 (got this during install, but it went away when I switched to the    
xfs-sources(2.4.18)....   
    
I discussed this with Joachim (migrating XFS to Gentoo) while testing his patch...But it's not only that...Going  
back to gentoo-sources gave me trouble with:    
    
a. the time-outs on my NIC (eepro100) back    
        [kernel] eepro100: wait_for_cmd_done timeout!    
b. wacom-tablet stops working:    
        [kernel] wacom_intuos_irq: received unknown report #1    
c. My VGA-console gets f#^&-ed up (seems something wrong with the last line, after that diagonal output !            
   (although funny at first, very annoying quite quickly ;-)      
   
 
Is there more going on ?

The Intel-made driver is supposedly of inferior design-quality, but does not
exibit this bug. I've installed it as a module, and the problem seems gone. See:

[Comment 6 Brandon Low (RETIRED) 2002-09-06 17:28:51 UTC]

what is the status of this bug?  Has this been tested in more recent gentoo
kernels (preferrably gentoo-r9)

[Comment 7 Brandon Low (RETIRED) 2002-10-01 08:05:49 UTC]

I'm assuming it works in 2.4.19-gentoo-r9, please re-open the bug if that is a
bad assumption
