Subject: Xen 4.1 + 3ware 9690SA = rejecting I/O to offline device
Date: Mon, 11 Oct 2010 17:44:56 -0400 [thread overview]
Message-ID: <4CB38558.5060207@theshore.net> (raw)
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.
