Hello list,

I'm using gentoo Linux with xen 3.4.1 and linux kernel 2.6.30 fine till
now where I need more RAM. I used 2GB and now I want to use 4GB.
But upping eth0 (4-port e100 Quad Port Device by Compaq) crashed the
kernel. I tried xen 4.0.0 with linux kernel 2.6.32-r1 from
http://code.google.com/p/gentoo-xen-kernel/downloads/list same error.
Using swiotlb=force or swiotlb=128,force or iommu=off did not succeed
even. The board has a tg3 gigabit NIC eth4, too. Upping this device does
not crash the kernel.
It must have something to do with e100 driver.
The machine where the crash happens is a Dell PowerEdge 840. It uses Intel
Core2Duo (dual core).

Can anyone help?

Here is some crash information:
------------------------
kernel BUG at lib/swiotlb-xen.c:454!
[<ffffffff80481120>] e100_rx_alloc_skb+0x190/0x230
...
RIP [<ffffffff803c56a6>] swiotlb_sync_single_for_device+0x96/0xe0
Segmentation fault
------------------------

Thanks for your help,
Daniel
