[Xen-bugs] [Bug 770] New: Cannot reliably use disk on disk controller of
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=770
Summary: Cannot reliably use disk on disk controller of a JS21
Product: Xen
Version: unstable
Platform: PPC
OS/Version: Linux-2.6
Status: NEW
Severity: critical
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: jimix@xxxxxxxxxxxxxx
The JS21 has a unique SDA controller than our other machines that use IDE.
The disk can be mounted and some disk activity succeeds but using it as rootfs
cause random user application failures.
I'd love to blame the IOMMU (U4 rather that the U3 on our IDE machines), but
net activity is stable and has been pushed pretty hard, we currently use
nfsroot file systems for JS21 with good results.
