>Description:
After waking up from APM standby mode, the IDE interfaces are reset, and
my Secondary Master (ad2), which was in UDMA 66 before, is in UDMA 33
mode henceforth.
dmesg:
resumed from suspended mode (slept 00:00:01)
ata0: resetting devices .. done
ata1: resetting devices .. ad2: DMA limited to UDMA33, non-ATA66 cable or device
done
ad2: DMA limited to UDMA33, non-ATA66 cable or device
I know for sure I have short 80-ribbon connectors for all drives,
and on initial boot-up everything is fine, dmesg again:
ad0: 58610MB <Maxtor 4W060H4> [119081/16/63] at ata0-master UDMA66
ad2: 43979MB <IBM-DTLA-307045> [89355/16/63] at ata1-master UDMA66
ad3: 19470MB <WDC AC420400D> [39560/16/63] at ata1-slave UDMA66
This cannot be cured with atacontrol:
# atacontrol mode 1 UDMA66 UDMA66
Master = UDMA33
Slave = UDMA66
options ATA_STATIC_ID is enabled.
Here's the list:
ATA channel 0:
Master: ad0 <Maxtor 4W060H4/AAH41310> ATA/ATAPI rev 6
Slave: no device present
ATA channel 1:
Master: ad2 <IBM-DTLA-307045/TX6OA6AA> ATA/ATAPI rev 5
Slave: ad3 <WDC AC420400D/J58OA30K> ATA/ATAPI rev 4
>How-To-Repeat:
apm -Z
dmesg
>Fix:
unknown. No workaround known other than reboot.
