Hi Jim and al,

I just noticed the two following loops:
flush_data_cache_local:
[...]

fdmanyloop:                                     /* Loop if LOOP >= 2 */
        ADDIB>          -1,%r31,fdmanyloop      /* Adjusted inner loop decr
*/
        fdce            0(%sr1,%arg0)
        fdce,m          %arg1(%sr1,%arg0)       /* Last fdce and addr adjust
*/
        movb,tr         %arg3,%r31,fdmanyloop   /* Re-init inner loop count
*/
        ADDIB<=,n       -1,%arg2,fdsync         /* Outer loop decr */

fdoneloop:                                      /* Loop if LOOP = 1 */
        ADDIB>          -1,%arg2,fdoneloop      /* Outer loop count decr
*/
        fdce,m          %arg1(%sr1,%arg0)       /* Fdce for one loop */

fdsync:
        syncdma
        sync
        mtsm    %r22
        bv      %r0(%r2)
        nop
        .exit

        .procend

[...]

flush_instruction_cache_local:
[...]

fimanyloop:                                     /* Loop if LOOP >= 2 */
        ADDIB>          -1,%r31,fimanyloop      /* Adjusted inner loop decr

        fice            0(%sr1,%arg0)
        fice,m          %arg1(%sr1,%arg0)       /* Last fice and addr adjust
*/
        movb,tr         %arg3,%r31,fimanyloop   /* Re-init inner loop count
*/
        ADDIB<=,n       -1,%arg2,fisync         /* Outer loop decr */

fioneloop:                                      /* Loop if LOOP = 1 */
        ADDIB>          -1,%arg2,fioneloop      /* Outer loop count decr
*/
        fice,m          %arg1(%sr1,%arg0)       /* Fice for one loop */

fisync:
        sync
        bv      %r0(%r2)
        nop
        .exit

        .procend


Do you think that could be there where the pb occurs?

Thanks for advise,
    Joel
