Can you provide a disassembly of the affected function, as
well as readelf -w for it? (An alternative for the latter would
be a systemtap build-tree run of loc2c-test against the same
module+address, but this is an undocumented diagnostic program.)
Is your kernel compiled with an unusual toolchain? -mregparm=3
may be related.
I wouldn't expect it, but does println($p1) give a different dump
for $p1 than $$parms? Does "stap -P ..." make a difference?
