Hi,
it's a 64-bit 133MHz PCI-X.
see
http://www.supermicro.com/products/motherboard/Xeon800/E7520/X6DH8-G2+.cfm
There must be something different about the way the kernel and its
components are composed and unfortunately I don't have the knowledge to
find it. Under the kernel that came with CentOS (2.6.9) the controller
works perfectly, it's only the 2.6.16 that comes with xen that produces
trouble. Is there any more debug options I could activate to provide
more details?
I don't want to move away from xen although I've already tried (the)
openvz (kernel), which works perfectly during high io load, but xen
seems more sympathic to me. I hope this messy technical detail doesn't
force me to change to a different product.
Thanks for any more hints!
ciao - Michael
