My NIC stops working after resuming from standby, it's not receiving any interrupts:

[Must have missed this message.]

I have a box with forcedeth that evidently works after a resume from
hibernation.  Unfortunately, so far I haven't been able to make the box
resume from suspend to RAM.  I'll do my best to try again tomorrow, but there's

Simon, I'd prefer the full dmesg to the grepped forcedeth messages.


It probably is.

With this applied, I can resume from standby *without MSI* and the 
NIC still works. I haven't tested it without MSI and without the 



If I have MSI enabled, it still doesn't work.

same problem with nv_shutdown about setting it to D3Hot?

Well, maybe.  The only way to verify that would be to try with MSI
disabled. ;-)

I'm not sure what you're asking here...?

This was a question for me. :-)

Hm.  I wonder if that's specific to forcedeth or other drivers may be affected.

I cannot reproduce the problem locally, at least not with 2.6.27-rc4.

I was able to make my box resume from suspend to RAM by using

# s2ram --force --vbe_mode --vbe_post

(s2ram as shipped in openSUSE 11.0) and forcedeth works correctly
after the resume.  However, I had to add 'acpi_sleep=old_ordering' to the
kernel command line.

My box is a desktop with an Asus A8N-SLI motherboard and an Athlon 64 X2 CPU.

I have created a Bugzilla entry for this issue at
http://bugzilla.kernel.org/show_bug.cgi?id=11390
Please put a boot log from dmesg and the output of 'lspci -vvv' in there, as
text attachments.

Thanks,
Rafael
