The similar issue has been discussed in adjacent thread "Machine reboot". Is it Intel
motherboard, or just carries Intel chipset ? Does building e1000 driver as a module and 'rmmod
e1000' just before reboot help ?

It's an Intel DG965RY board. I'll try out your suggestion on Monday.

Btw, are you using i386 or x86_64 architecture?

Hm, I'm also using x86_64 and 2.6.19-rc1-git9 works OK for me regardless of
e1000. 2.6.18 hangs if e1000 is built in.

Could you also try exactly 2.6.19-rc1-git9?

Will do, I'll try that on Monday also. I'd do it now, but obviously I
can't reboot the machine remotely...

2.6.19-rc1-git9 doesn't work any better for me. I haven't tried
unloading the e1000 module yet. Since I run the machine off an nfsroot,
it will require some creativity to test that.

You may try the following patch instead if it's easier for you. It'll likely break suspend stuff,
but you won't need to play around with modules.

I wouldn't do that like this, since e1000_suspend already does a pci_set_power_state()
right before it exits, and doing two of those closely after another might result in an
undetermined state.

I would be more interested in forcing D3 state instead of the current
`pci_set_power_state(pdev, pci_choose_state(pdev, state));` in e1000_suspend, so can you
try this instead?

diff --git a/drivers/net/e1000/e1000_main.c b/drivers/net/e1000/e1000_main.c
index ce0d35f..30ceeec 100644

pci_disable_device(pdev);

- pci_set_power_state(pdev, pci_choose_state(pdev, state));
+ pci_set_power_state(pdev, PCI_D3hot);

return 0;
}

alternatively, you can try PCI_D3cold or PCI_D0, but setting the device to D0 is a
no-op: the device is already in D0 at run-time, so that's silly.

In any case: this is not a driver bug, but really (unfortunately) a platform issue, so
this fix is not suitable for general cases *at all*, and we'd have to validate this
nasty workaround on all other chipsets that e1000 supports too, something that ain't
going to happen I'm sure.

constructive: I've just spend some time working with e100+suspend+shutdown+netconsole,
so I'll audit e1000 for that in the next few weeks and make sure that all works
properly. Perhaps that yields something for you.

But how this is different from original variant?
pci_choose_state(pdev, PMSG_SUSPEND) returns PCI_D3hot, and it is when LAN
in this state machine does not reboot. That's why I tried PCI_D0 in first
place (actually, I've originally just remove pci_set_power_state call at
all). I did not try PCI_D3cold, though.

Anyway, both patches are rather ugly, and will become even uglier with
checks for particular platform and system_state. I wish BIOS engineers fix
it 'the right way'.

To all that are seeing this problem:

can you send me (off-list is OK) the motherboard number+name, the BIOS versions (+ where
you downloaded them from) that you have tried and for each version, whether it worked
without this workaround or not?

Three days ago, Intel released a new BIOS version that claims to fix this issue.

I've tested it with 2.6.18 kernel which was unable to restart, it works now so
it seems that fix was successful.

I've got an Intel DG965RY with BIOS version 1250. That's the only BIOS
I've tried (I flashed it first thing when I got the machine), and the
workaround works.

this is incomplete information. Which version did you have before? what is your
motherboard number/name? etc. Please be complete.

Please provide what I asked for, if you can. I really need to know _everything_

Board name: DP965LT
BIOS version: 1458
2.6.18, 2.6.19-rc1 reboots OK.

BIOS version: 816
2.6.18 reboots OK.

BIOS version: 1162, 1176, 1250
2.6.18 cannot reboot. (rmmod e1000 causes reboot OK)
2.6.19-rc1 reboots OK (no additional patches)

I just tried the 1458 BIOS without the workaround and it's working fine.

okay, looks like the latest BIOS fixes it (hang on reboot/restart) for everyone. Thanks
for reporting back in, I'll make sure my colleagues write this down for everyone.

Mine was Intel DG965WH with the same BIOS version. I don't have the board currently, but I'll try
to retest if it comes to my hands one more time.

Subject: e1000 driver problems

Hello,

I have laptop thinkpad T61 with 82566MM Gigabit Network Connection (rev 03)
(8086:1049). I have kernel 2.6.24-rc3. E1000E driver does not work (the card
is not detected although it is PCI-E), with E1000 driver, it works mostly OK
unless I force speed to 100Mbits. (ethtool -s eth0 autoneg off speed 100)

I got message about device hang:

and so on.

Is it known problem?

this device (the ich8 onboard NIC) will not be supported in e1000e until 2.6.25.

there have been indeed know reports of these "fake" hangs. basically the counter
logic for these newer devices reports hangs too quickly for 10/100 speeds while
they actually are not occurring (the line is just very busy).

The fix for this has been to grant more time for the hardware to recover from this
busy state. I'll make sure to check if the upstream drivers are OK in this regard.

you can try our out-of-tree e1000 driver (7.6.x or newer) which should work OK for
you with respect to this problem. Please give that a try.

Cheers,

Auke

unfortunately, the 7.6.9 driver cannot be compiled with 2.6.24-rc3-git2
kernel due to compilation errors.

but the in-kernel version of e1000 supports the ich8 lan device just fine and can
be builtin. also this kernel has the first release of e1000e which supports the
ich9 onboard lan device.
