Comment 1 Tejun Heo 2009-01-26 17:30:48 UTC
Does "pci=nomsi" make any difference?
Comment 2 Nicolas Derive 2009-02-01 08:03:50 UTC
No, it doesn't make any difference... :/
Comment 3 Nicolas Derive 2009-02-01 11:15:05 UTC
Sorry, I spoke a little bit too fast... It works !!! But should I keep this option for ever or what ? And where was the problem ? Thanks for your help !!

Can you please do "lspci -nnvv"?

Comment 8 Tejun Heo 2009-02-11 17:39:35 UTC
Peer Chen, ahci is failing on mcp78s due to broken MSI. Can you please tell me whether MSI should be disabled on the whole system or disabling it on ahci is enough? ie. Is MSI broken in the bridges or is it the ahci controller itself? Thanks.
Comment 9 TJ 2009-03-02 12:58:28 UTC
I've got a user on Ubuntu, using both the Jaunty alpha 2.6.28- and our packaged vanilla mainline 2.6.29- kernel, that is suffering 'lost disk on resume' syndrome with the Nvidia MCP78S [10de:0ad0] unless the "pci=nomsi" work-around is specified. We have some comprehensive logs and the user is keen to help in resolving the issue properly. https://launchpad.net/bugs/334644
Comment 10 Tejun Heo 2009-03-02 16:24:41 UTC
Hey, tj, I'm a tj too. Nice to meet you. :-) I'll ping pchen via email one more time and then just blacklist the whole system. Hmm... if anyone is willing to, this can be verified by putting in a MSI capable device and see whether it works without pci=nomsi. e1000e is a good test card for this purpose. Thanks.
Comment 11 Peer Chen 2009-03-02 18:50:08 UTC
we have a patch for MCP78 MSI issue and kernel 2.6.28 had include it. https://lists.ubuntu.com/archives/kernel-team/2008-February/002449.html The patch code is in drivers/pci/quirks.c and looks like kernel resume code doesn't invoke the patch routine in quirks.c.
Comment 12 Tejun Heo 2009-03-02 19:07:35 UTC
Thanks for the pointer Peer Chen. Nicolas, Tj, can you guys please try the patch? Adding call to it during resume path can be easily done adding another fixup declaration, so no worries there.
Comment 13 Nicolas Derive 2009-03-21 08:12:03 UTC
Is the patch included by default ? I tried to delete the "pci-nomsi" option at booting one time using 2.6.28-11.36 kernel in Jaunty (devel version), and got the same problem that I had, and fell down to a busybox.
Comment 14 Nicolas Derive 2009-03-21 08:12:45 UTC
I was meaning the "pci=nomsi" option of course... Sorry for the mistake.
Comment 15 TJ 2009-03-21 17:30:42 UTC
The patch referred to by Peer Chen looks to have got lost in the noise. That may be because it appeared as a 'reply' to another email. Is there an upstream commit we can cherry-pick? If not, I'll propose the patch for inclusion as a temporary fix until upstream receives it.
Comment 16 Tejun Heo 2009-03-22 19:29:52 UTC
The upstream commit is 9dc625e72309e1c919ea3e7f51d0ffca96123787. Is someone interested in testing suspend/resume and whether RESUME is necessary there too?
Comment 17 TJ 2009-03-22 22:23:44 UTC
OK, found it now. That commit is in the Ubuntu kernels since v2.6.25-rc3 (Intrepid 8.10 and Jaunty 9.04). So the concern is that it isn't being invoked on resume?
Comment 18 Peer Chen 2009-05-06 02:58:04 UTC
Any kernel patch to add the call to quirks code in resume path?
Comment 19 Tejun Heo 2009-05-08 23:34:22 UTC
Created attachment 21284 [details] ht-msi-quirk-on-resume.patch Sorry about the delay. Patch attached.
Comment 20 Peer Chen 2009-06-30 02:53:19 UTC
Tejun, Thanks, the patch works, could you help to submit it?
Comment 21 Tejun Heo 2009-07-08 05:11:01 UTC
Patch submitted. Thanks. http://lkml.org/lkml/2009/7/8/32
Comment 22 TJ 2009-07-09 10:12:03 UTC
Thanks for that Tejun. I'll try to get it pulled into the existing Ubuntu releases as well as the forthcoming Karmic release.
