atapci VIA 82C596B UDMA66 controller: problem for 5.X ?

Rob,

I am currently running 5.3 Release on a Tyan Trinity 400 (VIA 82C596B 
UDMA66) with 2 x Seagate Barracude IV (UDMA100) and have no stability 
issues. e.g from dmesg:

atapci0: <VIA 82C596B UDMA66 controller> port 
0xe000-0xe00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0
ata0: channel #0 on atapci0
ata1: channel #1 on atapci0
ad0: 19092MB <ST320011A/3.10> [38792/16/63] at ata0-master UDMA66
ad1: 19092MB <ST320011A/3.10> [38792/16/63] at ata0-slave UDMA66
acd0: CDRW <CREATIVE CD-RW RW8439E/1R09> at ata1-master PIO4

What does your dmesg show if you dont force ata_dma=0?

Hmmmm - you have an IBM disk in one pc and WDs in the other, hard to 
believe that the disks are the issue. Do both pcs have the same mobo? 
(if so what is it).

Something else - did you upgrade from 4.x or fresh install?


With respect to attempting a fix, you could try

$ atacontrol mode 0 UDMA66 UDMA66

immediately after boot, to see if you can force a sensible transfer mode 
setting.

regards

Mark

atapci VIA 82C596B UDMA66 controller: problem for 5.X ?

Hey Rob,

I'm on the same hardware - 82C596B (UDMA66) - but using a Seagate 20GB
UDMA100 Drive.  Relevant info from dmesg:

atapci0: <VIA 82C596B UDMA66 controller> port
0xd000-0xd00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0
ata0: channel #0 on atapci0

ad0: 19092MB <ST320014A/3.07> [38792/16/63] at ata0-master UDMA66

sysctl -a shows:
hw.ata.ata_dma: 1
hw.ata.wc: 1
hw.ata.atapi_dma: 1

I'm using 5-stable now but didn't have problems when using
5.3-release.  Flakey hardware?

Dennis

At initial bootup, I get some UDMA error messages,
several lines with something like:

  READ_DMA UDMA ... ICRC error ... LBA....

then the kernel panics and the system reboots;
the same error messages occur again etc. etc.
ad infinitum.

I have put this into the file '/etc/rc.early',
and that works. So then, after bootup, I get:

  # sysctl hw.ata.ata_dma
  hw.ata.ata_dma: 0
  # atacontrol mode 0
  Master = UDMA66
  Slave  = BIOSPIO


What does that mean? UDMA66 and hw.ata.ata_dma=0 ?

And why then is UDMA66 not automatically choosen
at bootup?

Thanks,
Rob.

- run diskinfo -t on your disks and let us know the results
- use sysctl to set hw.ata.ata_dma=1 and see what happens

At a guess I would suggest that dma is broken for your motherboards in 
5.3 (what were they again?).

Is there a risk that I lose all data on my disk, when
changing this in the BIOS?

BTW: During the fresh FreeBSD install, I have never
encountered a choice for formatting with or without
LBA. In the Fdisk window, I choose 'use entire disk
for FreeBSD', and in the partition window I have set
'newfs' for all partitions.

Thanks,
Rob.

atapci VIA 82C596B UDMA66 controller: problem for 5.X ?

Hi,

I have two PCs, with apparently a somewhat old
motherboard, since there's a maximum support for
UDMA66 by the harddisk controller.
The attached harddisks are newer and allow a
higher speed of UDMA100.

This combination of older motherboard and newer
harddisk causes great problems with 5.X (it never
did with 4.X). I have irregular crashes of X and
even crashes at initial bootup. All this is solved
by using  hw.ata.ata_dma="0", which forces the
harddisk to use the very low speed of PIO4 :(.

Both PCs have a VIA 82C596B UDMA66 controller.
I wonder if that is the problem for 5.X ?

On these two PCs, the output is of
   grep -i ata /var/run/dmesg.boot
is:

-- PC1 -------------------

I consider this a serious drawback of 5.3.

Any idea how this can be resolved?

Best regards,
Rob.
