Additional information: Orran and I have modified xen to show all hcalls made by domains other than 0 and idle. In addition we are not showing hcall x20, event channel operation (because we get one for every character put to the partition console.)

Should the code below also show HSRRs?

Been doing a binary search to find at least one of the things causing a crash. What I have now is that the following call from libOS reliably crashes xen.

the call is:
                rc = hcall_read(ret, flags, idx + i);
In the library OS , with parameters:
flags - 0, idx = 0 ret = 240948

That coems into xen as hcall "c" with the following registers:
