Hello,
I''m having trouble during high IO activities:
Oct 8 10:38:51 matrix kernel: irq 16: nobody cared (try booting with
the "irqpoll" option)
Oct 8 10:38:51 matrix kernel:

Oct 8 10:38:52 matrix kernel: Disabling IRQ #16
Sometimes it''s also irq 17. Of course I tried irqpoll, but no use.
Currently I''m using ''noirqbalance noirqdebug'' as
kernel parameters as
these two reduce the above messages, but they still occur.
Data written on disks seems to be alright, and I think, this doesn''t
concern my controller, but it''s strange anyways.
This doesn''t arise with my distribution''s stock kernel, just
with xen.
My setup: Supermicro X6DH8-G2+, 3ware 9550SXU-4LP, 4GB RAM, xen-3.0.2-2
(i.e.linux-2.6.16)
Any ideas?
TIA - Michael

Seems to be an issue between newer Motherboards / BIOSs and 2.6.16 / 2.6.17 kernels. I see this message on my nForce 590 system (Asus M2N32-SLI Deluxe motherboard) as well. Usually an "IRQ7 nobody cared" message under Gentoo 2.6.17. Rumored to be fixed by a newer developer-only BIOS for this particular board, or possibly fixed in 2.6.18. But since it doesn''t seem to affect anything, it''s merely a minor annoyance. Xen 3.0.2 also had a terrible time running on this particular system, so it''s still running a Gentoo 2.6.17 kernel. It''s probably not Xen-specific for your motherboard and installing another Linux kernel will show the same message. (Until you either upgrade to a newer Linux kernel or you upgrade to a BIOS that plays nicer with Linux.) I am a bit surprised that you don''t see it with your distro''s stock kernel. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I posted it to the lkml, but I think they''ve got other stuff to do than caring of old (2.6.16) stuff like this. However, I''ve seen quite some lkml threads discussing about irq balancing. Glad to hear from somebody who also judged it to be harmless.

Since Asus released a new version of their BIOS this week for the motherboard where I''m seeing this issue, I''m hoping that I can get it to go away for good now. When I researched the "nobody cared" message a few months ago, I found references going back to 2002. Seems like it crops up periodically with various motherboards over the years. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
