Hmm. I haven't been able to reproduce this here on any of the
Seagate drives I have access to. Many of them are U160 Cheetahs,
but not the exact same model you have. One thing that might help
me is a dump of the message buffers in two places:
1) aic7xxx.c: ahc_contstruct_ppr(). After the message is constructed,
printout the contents:
ahc->msgout_len += 8;
printf("Constructed PPR Message: ");
for (i = 0; i < ahc->msgout_len; i++)
printf("%c ", ahc->msgout_buf[i]);
printf("\n");
2) aic7xxx.c: ahc_parse_msg(). In the MSG_EXT_PPR case just after we've
pulled in all bytes:
if (ahc->msgin_index < (MSG_EXT_PRR_LEN + 1)
break;
printf("Incoming PPR Message: ");
for (i = 0; i <= ahc->msgin_index; i++)
printf("%c ", ahc->msgin_buf[i]);
printf("\n");
