I couldn't check with 1030 but with mptsas, with SATA drives with the patch sent by Eric, I am able to see the err_cnt not getting incremented to 1.
Can you please add some debug prints in the mptscsih_io_done before calling sc->scsi_done(sc); to print the command if the result is a non zero. Like the one below.
if(sc->result)
scsi_print_command(sc);
And print the sensekey, ASC,ASCQ in mptscsih_copy_sense_data
printk("SK %x ASC %x.. ASCQ %x\n ",sense_data[2], sense_data[12],sense_data[13]);
And send me the log offline, It should tell you which command is failing.
Thanks
Sathya

I see the same problem with LSI53C1030 with SCSI disks attached. So it might not be a SATA-only problem.
Thanks!
