$ fgrep 1220 include/asm-ia64/unistd.h
#define __NR_getxattr                   1220

Apparently, your libc is making getxattr() system calls, but the
kernel doesn't understand them.  The kernel reacts by printing the
"sc1220" message and returning ENOSYS.  The messages are harmless
(apart from being annoying, I suppose).
