Hi Soeren, Hi all,
it seems to me that ATA TQ is working again with -current as of
yesterday :-)
My disk is on
"atapci0: <VIA 82C686b UDMA100 controller> port 0xc000-0xc00f \
at device 7.1 on pci0"
It's an
"ad0: 43979MB <IBM-DTLA-307045> [89355/16/63] at ata0-master UDMA100"
Even if it's obviously not reported as TAGGED, it seems to work as such:
'atacontrol cap 0 0' reports:
"ATA channel 0, Master, device ad0:
ATA/ATAPI revision 5
device model IBM-DTLA-307045
serial number YMDYMH21528
firmware revision TX6OA50C
cylinders 16383
heads 16
sectors/track 63
lba supported 90069840 sectors
lba48 not supported
dma supported
overlap not supported
Feature Support Enable Value Vendor
write cache yes no
read ahead yes yes
dma queued yes yes 31/1F
SMART yes no
microcode download no no
security yes no
power management yes yes
advanced power management yes no 0/00
automatic acoustic management yes no 254/FE 128/80"
So 'write cache' is disabled and 'dma queued' is enabled, right?
At least my 'standard test' (which is a 'tar cvf /dev/null /disk/ports')
is not able any more to switch the disk to PIO-Mode - which I tried
repeatedly ;-)
The only thing I saw were 1,2 stops of about 500ms during the listing of
the tar-command but nothing worse happened. With earlier Kernels this
indicated a soon lock and switch to PIO...
Fine! I hope this stabilizes...
