here are a list of the files with fully qualified paths. i have also fixed them on my system and am attaching the fixes (which are simple hacks to avoid random results and to get the compiler to be quiet... but better than it is now). file: arch/i386/mach-generic/../mach-es7000/es7000plat.c (appears it could be used uninitialized) line: 193 var: std.count uninitialized file: arch/i386/kernel/cpu/transmeta.c (really could be used uninitialized) line: 37 var: cpu_freq file: ipc/msg.c (compiler noise) line: var: setbuf.qbytes, setbuf.uid, setbuf.gid, setbuf.mode file: ipc/sem.c (compiler noise) line: var: setbuf.uid, setbuf.gid, setbuf.mode file: fs/jfs/jfs_txnmgr.c (appears by inspection that it could leave a linked list improperly terminated) line: var: pxd.addr1, pxd.addr2, pxd.len file: fs/udf/balloc.c (potential bug in filesystem by inspection) line: var: goal_eloc.logicalBlockNum file: fs/udf/super.c (potential bug by inspection) line: var: ino.partitionReferenceNum file: fs/xfs/xfs_bmap.c (compiler noise) line: var: rtx file: arch/i386/kernel/microcode.c (compiler noise) line: var: new_mc bug fixes follow in additional information for each of these. some are not elegant but perserve the behavior of the existing code but eliminate the potentially random condition. Reproducible: Always Steps to Reproduce: 1. repro is easy if you recompile the kernel and >log just these errors will report to the console 2. 3. es7000plat.c changes... add line 168: sdt.count = 0; transmeta.c changes... add line 21: cpu_freq = 0; msg.c changes... add lines 395-398: setbug.qbytes = setbuf.uid = setbuf.gid = setbuf.mode = 0; sem.c changes... add lines 865-867: setbuf.uid = setbuf.gid = setbuf.mode = 0; jfs_txnmgr.c changes... add lines 1925-1927: pxd.len = 0; pxd.addr1 = 0; pxd.addr2 = 0; balloc.c changes... add lines 754-756: int goal_eloc_initialized = 0; /* this is at the end of the variable declations */ goal_eloc_.logicalBlockNum = 0; add lines 809: goal_eloc_initialized = 1; /* this is at the end nspread < spread conditional block */ add lines 827-833: if( goal_eloc_initialized == 0 ) { udf_release_data(goal_bh); mutex_unlock(&sbi->s_alloc_mutex); *err = -EDQUOT; /* not sure if this is the right error but it is a valid error */ return 0; } /* this stuff is added right before the line of code that reads... newblock = goal_eloc.logicalBlockNum; */ super.c changes... add line 1364-1366: int partition_initialized = 0; ino.partitionReferenceNum = 0; add line 1389: partition_initialized = 1; /* at the end of conditional block that starts with j != 1 */ add line 1400-1401: if( partition_initialized == 0 ) return 1; xfs_bmap.c changes... move line... xfs_rtblock_t rtx; (near 2620 in declarations for xfs_bmap_rtalloc) to 2660 inside the scope of the conditional block (ap->eof && ap->off == 0) where it is used and initialized it to zero. xfs_rtblock_t rtx = 0; microcode.c change line 387 by adding an initialization to so it reads... void *new_mc = 0;
Sorry, I have no clue what's this bug about. Whatever it is, needs to be submitted upstream (as a unified diff, not as a description what to do :)
it's obviously about the kernel eric: this sort of thing is best handled by e-mailing LKML with patches ... otherwise people will eventually fix it
