I have problem with ATA drive having DMA TIMEOUTs.
It might work day or two fine with DMA mode on but then system halts on
those dma timeout problems.
hardware is:
atapci0@pci2:5:0: class=3D0x018085 card=3D0x4d68105a chip=3D0x4d69105=
a
rev=3D0x02 hdr=3D0x00
vendor =3D 'Promise Technology Inc'
device =3D 'PDC20269 Ultra133 TX2 EIDE Controller'
class =3D mass storage
and PDC20269 is on supported list (5.4-RELEASE).
and has one 160GB drive in it. When I first got this problem I tried change
cable, changed drive to another similar one and moved drive to different
place on card. No help. Now it has been running on PIO mode about a year
without any problems at all.
So I wonder if there actually is some problem in ata drivers and is there
maybe any fixes on those drivers in new releases? So would upgrade to 5.5 o=
r
6.1 help on this? upgrade from 5.3 to 5.4 didn't help...
I can actually run it on PIO-mode but sometimes DMA could give little more
speed so if you would be cool if I can get it work with DMA mode on.
