With gcc-4.8: static inline int wait(void) { do { load_wait_psw(0x0102000180000000ULL, &S390_lowcore.external_new_psw); 331e: e3 20 d0 00 00 04 lg %r2,0(%r13) 3324: a7 39 01 b0 lghi %r3,432 3328: c0 e5 ff ff fb ac brasl %r14,2a80 <load_wait_psw> if (S390_lowcore.ext_int_code == 0x1004) 332e: e3 10 00 86 00 91 llgh %r1,134 3334: a7 1e 10 04 chi %r1,4100 3338: a7 84 00 0a je 334c <sclp_wait_for_int+0x9c> return ETIMEOUT; } while (S390_lowcore.ext_int_code != 0x2401); 333c: a7 1e 24 01 chi %r1,9217 3340: a7 74 ff ef jne 331e <sclp_wait_for_int+0x6e> return 0; 3344: a7 28 00 00 lhi %r2,0 3348: a7 f4 00 04 j 3350 <sclp_wait_for_int+0xa0> That does look much better for 3338, 3340, not really for 3348 (to 3350). It does fix the issue at hand, but it's a band-aid at most. I installed the package on wheezy (compiled on sid) and it booted...
