------- Comment #6 from fthain@telegraphics.com.au 2011-09-15 00:41 -------

This bug also affects an IBM x3550 server I've been maintaining. dmesg and xm
dmesg attached. Some specs:

Gentoo Hardened amd64 Xen-4.1.1

dom0 linux-2.6.32.45 kernel from Jeremy Fitzhardinge's xen/stable-2.6.32.x
branch commit 20a27c1e25b8550066902c9d6ca91631e656dfa3

There's no problem running vanilla 2.6.32.45 on bare metal.

The machine seems to be running OK with the above configuration (in testing for
14 hours and no crash yet, see first attachment), but when it was running Xen
4.0.1 and an earlier 2.6.32.24 dom0 build from xen-stable/2.6.32.x, the aacraid
driver failed immediately (see second attachment) in the same way reported by
others (apparently DMA buffer exhaustion):

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=596419

I'm a bit concerned that it will fail again. Can anyone recommend a suitable
value for swiotlb argument? Is it likely to help?

Here's some specs, in case it helps...

------- Comment #8 from konrad.wilk@oracle.com 2011-09-15 01:37 -------
So.. why are you not using the default values (64MB)

I see you have swiotlb=128 which ends up with:

DMA: Placing 0MB software IO TLB between ffff880020000000 - ffff880020040000
DMA: software IO TLB at phys 0x20000000 - 0x20040000

which of course means that there is not enough space. 0MB will
cause issues like this. The parameter (if you look in the
kernel-parameters.txt) defines it as -pages_, not megabytes.

So either leave it as default, or change it to larger value, like swiotlb=65535
