Yes, eepro100.c. Let me know if I can test something, although I would
need a reproducible testcase also. Still doing some tests with high
network load, as this caused the similar lockup in the other thread.

Perhaps this will help.  Yesterday we had a strange error on an eepro100
NIC.  System is 4-way Xeon, 4G RAM, 4 eepro100 nics (2 in use), Dell PE6400.
Kernel is 2.4.17, no additional patches.  The system has not locked up
though.

The error was

RE: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)

[Robbert Kouprie]

Not much new, but still:

Today I got the same problem again with 2.4.18-pre3-ac2. Network
connections stuck, NFS mounts stuck. Bringing down/up the interface
doesn't help. Seems like the NIC is really in trouble here. Only a
reboot would bring the nick back in use.

Still no testcase though, and I have no idea on how to investigate this
:(
Can anyone give a hint as where to seek?

How about www.kernel.org? Download _latest_ kernel-patch (-pre7) and tell us
about it. As long as you are trying only old pre's there is not much of
a chance any important brain will listen to you.

RE: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)

[Robbert Kouprie]

Thanks for your reaction Stephan, but I seriously doubt the change below
would fix the problem... Also, as the problem appears randomly, and
usually after some uptime, I obviously can not know about it being fixed
if I constantly upgrade the kernel. I'd rather wait and see if it
appears again in time after I did a kernel upgrade, and not trying every
-pre while there's no mention on the mailing list of such bug being
fixed.

Anyway, I just rebooted with 2.4.18-pre7-ac1, we'll see if it helps.

Hello Robert,

Well, I know the changes to the driver are rather ... small :-)
But on the other hand, I would not be all that sure that the bug is a
hundred percent related to the driver itself.
I run a working config with eepro100-driver, btw.

Regards,
Stephan

Re: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)

[Ben Greear]

What does the rest of the hardware-config look like?  Is
the NIC attached to a 10bt hub?  Are you using PCI-Riser
cards?

The box is an Abit BP6 with Dual Celerons 433 and 192 Mb RAM. No
PCI-Riser cards. It is connected at 100 Mbit full duplex to a 100
Mbit switch. APIC is enabled. No kind of power management is enabled.

The only lockup problems I have run into are connecting some eepro nics to
a 10bt hub, and using (cheap arsed, it appears) PCI riser cards.  I have
heard of some SMP related issues, but nothing concrete, and I don't
have any SMP systems personally.  You could try the e100, but I have
no idea if it will be better or worse for your particular problem.

RE: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)

[Robbert Kouprie]

I experienced the 10 Mbit half duplex problems too with this card, but
they seemed to have gone away after a bugfix from Alan Cox somewhere in
2.4. Somewhere later I upgraded to 100 Mbit full duplex and never
experienced problems again until 2.4.17.

I think im gonna try some older kernels and look through diffs if I have
time.

PCI Problems [was Re: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)]

I was running into the same problems here; SMP system w/PCI riser card
(HP NetServer LPr), connected to a 10/100 switch. I'd get
"wait_for_command_timeout" errors all the time under moderate network
load. Switching to the e100 driver didn't help in the slightest.
Eventually, I'd experience a complete system lockup.

Replacing the card with a 3c59x-based card put the machine back in
service (I've completely written eepro100s off as a viable cards now),
although I still saw occasional PCI-related issues. Specifically:

Jan 23 10:11:37 x kernel: Uhhuh. NMI received. Dazed and confused, but
trying to continue
Jan 23 10:11:37 x kernel: eth0: Host error, FIFO diagnostic register
0000.
Jan 23 10:11:37 x kernel: eth0: PCI bus error, bus status 80000020
Jan 23 10:11:37 x kernel: You probably have a hardware problem with your
RAM chips
Jan 23 10:11:37 x kernel: eth0: Host error, FIFO diagnostic register
0000.
Jan 23 10:11:37 x kernel: eth0: PCI bus error, bus status 80000020

The last two messages will repeat indefinitely, usually with a hit to
the dist for each pair of log entries (resulting in a very distinctive
drive grinding). Memory problems don't seem to be the issue; with a
fairly extensive run of memtest86, everything came back clean.

Taking a few minutes to try and rectify the situation, I started
shutting down services and manually unloading modules to see what was
causing the problem. Unloading usbcore did the trick:

Jan 26 18:41:24 x kernel: eth0: Host error, FIFO diagnostic register
0000.
Jan 26 18:41:24 x kernel: eth0: PCI bus error, bus status 80000020
Jan 26 18:41:24 x kernel: eth0: Too much work in interrupt, status e003.
Jan 26 18:41:24 x kernel: usb.c: USB disconnect on device 1
Jan 26 18:41:24 x kernel: USB bus 1 deregistered

I've rebooted the machine since then, but have always unloaded usb-uhci
and usbcore after booting. The issue hasn't cropped up again, although
it happened every couple of days previously.

The kernel in question is Red Hat's kernel-smp-2.4.9-21 build.

Odd, I've got an HP LPr with an     Ethernet controller: Intel Corporation
82557 [Ethernet Pro 100] (rev 8). on the riser.  Works fine for me under
the debian SMP kernel Linux version 2.4.5-686-smp (herbert@gondolin) (gcc
version 2.95.4 20010319 (Debian prerelease)) #1 SMP Sun May 27 18:32:54

system is relativly low memory though.

Re: PCI Problems [was Re: NIC lockup in 2.4.17 (SMP/APIC/Intel 82557)]

[Ken Brownfield]

I've had LPr, LP1000r, LP2000r, and LH6000s in *heavy* production for
two years straight with nary a whimper from the eepro100, e100, or e1000
drivers.*  This is SMP with 2-6 procs, 256MB-4GB RAM, all 2.2 and 2.4
kernels under RH6.2.  On 100/1000, never 10Mb though.

Not to say that the HPs smell like roses, but I would highly suspect bad
hardware or a suspect BIOS/PCB revision, etc. in this case.

Just my US$0.02,

Ken.
brownfld@irridi.com

* besides a quirky arp issue on boot that seemed to go away on its own
and wasn't card-specific.  And the long-standing I/O APIC issues. ;)

Your machine took an NMI and a PCI bus diagnostic. That generally points
hard to a bus problem.
