Find an poke this in as an initial test...........
I find that this works on 2/4 chipsets that I have to test with under SMP. PDC20246 appears to stablize but no DMA transefers are allowed. HPT343 (unreleased chipset specific) appears to stablize with Fast-ATA enabled, but no DMA transefers are allowed.
Both Intel and AEC6210 still have troubles, IMHO.
I just grabbed a Colorado 8GB Drive over the weekend for home use. Something to backup and test with, also.........
Note that using the native software under MSDos 6.22, it flys at about 34MB/minute uncompressed on the Intel-chipset.
static void idetape_setup (ide_drive_t *drive, idetape_tape_t *tape, int minor) {
drive->ready_stat = 0; /* An ATAPI device ignores DRDY */ - drive->dsc_overlap = 1; + drive->dsc_overlap = (drive->id->capability & 0x20) ? 1 : 0; + +#if IDETAPE_DEBUG_LOG + printk (KERN_INFO "ATAPI overlap : %sabled.\n", + drive->dsc_overlap ? "en" : "dis"); +#endif /* IDETAPE_DEBUG_LOG */
