In an effort to fix the problem described in my previous xen-devel post
("New CPUS, now get: NETDEV WATCHDOG: eth0: transmit timed out"), we've
come across another problem. 3ware 9690SA cards to not behave under Xen
4.1 (as of cs 22155).
We have a simple Xen thrash test suite which fires up domUs that do
different workloads (some swap thrash, some kernel build, some spin
CPUs, some cycle rebooting, etc). Almost immediately after launching
the suite we can get the 3ware 9690SA card to fail with something like
the following:
sd 0:0:0:0: WARNING: (0x06:0x002C): Command (0x28) timed out, resetting
card.
sd 0:0:0:0: WARNING: (0x06:0x002C): Command (0x0) timed out, resetting card.
sd 0:0:0:0: rejecting I/O to offline device
sd 0:0:0:0: rejecting I/O to offline device
Under a 2.6.32 dom0 it sometimes also triggers Xenwatch like so:

Results matrix:
+---------------------------------------------------------------+
| Xen | Dom0 | 9550SXU | 9690SA | 9750 |
+---------------------------------------------------------------+
| 3.4.1 | 2.6.18.8-931-2 | OK | OK | OK |
| 3.4.4-rc1-pre | 2.6.18.8-931-2 | OK | OK | OK |
| 3.4.4-rc1-pre | 2.6.32.23-g41a85de5 | OK | OK | OK |
| 4.1 @ 22155 | 2.6.18.8-931-2 | OK | FAIL | OK |
| 4.1 @ 22155 | 2.6.32.23-g41a85de5 | OK | FAIL | OK |
+---------------------------------------------------------------+
The failures were verified on at least 2 machines of identical
specification.
The same dom0 kernels that produce a stable 9690SA under Xen 3.4, bomb
under Xen 4.1.

Hello,
i can confirm the same behaviour on xen 4.0.1, with a 3ware 9690SA card,
triggered by heavy I/O load. Does anybody know a possible workaround for the
issue?
Thank you very much.

Uhh, can you refer to the thread that explains "same behaviour"?

It might be related to "pci-passthrough in pvops causing offline raid" - look
in that e-mail thread and I posted a list of things I would like you to do
so that we can get to the bottom of this.

I'm back at this, and the problem still exists with a 4.1.1/3.0.4 stack.
Konrad, in the "offline raid" thread you asked for the following debug
information:
http://www.theshore.net/~caker/xen/BUGS/offline-raid/
The sysrq-t.txt and triple-a-star.txt outputs are after I got the raid
card to hang up (but before it timed out and started spewing to the
console).
Oddly, lspci shows three devices assigned IRQ 16, however
/proc/interrupts only lists two of them. Side effect of MSI?
Also, the problem still happens even with MSI disabled (pci=nomsi).
Thanks,
-Chris

This is almost certainly the bug to do with not ack'ing a migrating line
level interrupt which I fixed in c/s 23145:1092a143ef9d. Try applying
that patch, or just running from the tip of

That was it! You're a champion.
