(NET EEPRO100) Update to kernel hoses networking on Acer Travelmate
Last modified: 2013-07-02 22:06:02 EDT
Description of Problem:
Kernels 2.4.9-31 and 2.4.9-21 make ethernet interface (eepro100) in
Acer Travelmate laptop unusable.
I have here now such laptop where top of 'dmidecode' output shows
DMI type 0, 19 bytes.

It has a built-in ethernet card which is detected as eepro100

When trying to use with 2.4.9-31 (and at least 2.4.9-21) kernels from
7.2 distro updates ethernet connections go away rather quickly filling
logs with messages:
eepro100: wait_for_cmd_done timeout!
eepro100: wait_for_cmd_done timeout!
"Quickly" means in this context that an attempt to grab over NFS
a binary rpm of a kernel require multiple executions (three, four,...)
of 'ifdown eth0; ifup eth0' after which transfers usually resume.
ssh connection lock up unpredictably and often even before completing
a login sequence or soon thereafter.
'mii-tool -v' invariably shows:
eth0: no autonegotiation, 10baseT-HD, link ok
product info: vendor 00:aa:00, model 51 rev 0
basic mode: autonegotiation enabled

The only possible clue comes from 'eepro100-diag', which has to be
called with '-p 0x7000' as it is not finding the card by itself, which
gives that with '-mm' flags:

The EEPROM checksum is correct.

Sleep mode is enabled. This is not recommended.
Under high load the card may not respond to
PCI requests, and thus cause a master abort.
It is not clear what enables this "sleep mode" and how possibly to
The problem does not seem to occur with the original 2.4.7-10 kernel
from distribution CDs as I run the whole update of this installation
from an NFS mounted directory without any incidents.
It does not seem to be a problem of only a network driver as with
both incriminated kernels from time to time screen updates slow down
to ridiculous pace and one can see a terminal window "scrolling" in
distinct multiple "waves".
The current solution seem to be to replace the whole kernel with the
one from "skipjack" public beta. At least nominally the same version
of a network driver is in use. Still I just copied around 1.5 GB of
data from an NFS mounted directory to a destination on a laptop and it
survived. Not everything is perfect as there was one incident during
this transfer when a network temporary wedged but it recovered by
itself. I attach a dmesg output for this exercise. All transfers
are on my "home" network between machines sitting side by side on
Version-Release number of selected component (if applicable):
Created attachment 50004 [details]
dmesg output from an NFS session
On the less optimistic note just now an ssh session _to_ this laptop
running 2.4.18-0.4 wedged up and it does not look that it is going to
recover. :-( It is already few minutes with a dead network.
One more possible clue. After I did 'ifdown eth0; iup eth0' on a laptop
a network is back and dmesg reports a bunch of
eepro100: wait_for_cmd_done timeout!
("last message repeated 4 times" and "last message repeated 13 times")
eth0: 0 multicast blocks dropped.
I'm getting this same thing with kernel 2.4.8-0.16, under RH7.2. Everything
works fine after a reboot/startup, but after suspending and unsuspending, I get

(I hope bugzilla doesn't mangle this)
2.4.18-0.13 from the current "public beta" included e100 among "addon"
drivers. This one seems to work without going away after a while.
It also survives suspend.
The value of this report seems to be mostly historical. I did not hear
from the owner about network problems; but he is using e100 driver.
Ok, closing since e100 appears to work. We are deprecating eepro100
in favor of e100.
