Hello,
I'm using 2.4.20-ac2, when I boot the system, SATA disks on a sil3112
controller (IWill IS150-R) are detected, but dma is not enabled.
The disks work perfectly in raid 1 mode, and I can enable dma using
hdparm -X66 -d1 /dev/hda
hdparm -X66 -d1 /dev/hdc
But sometimes this fails and the entire system hangs. I suspect it
happens when I enable dma mode while there is some harddisk activity.
I tried 2.4.21-rc7-ac1 too, but the dma isn't enabled by default either.
If I can test some more, please let me know,
Regards,
Adriaan Peeters

That suprises me somewhat. 7-ac1 should force DMA on

These are Maxtor drives with SATA convertors ? If so make sure the
convertor is set for UDMA100 not UDMA133 mode. (See http://www.siimage.com
support pages)
Can you send me a dmesg from 7ac1 please

No, these are native SATA drives. The only jumper settings are the usual
master/slave jumpers, and slave mode is enabled (no jumpers). But that
shouldn't matter.

The system seemed to be stable for a few days, but then the following
happened:
- First I got read-only filesystem messages
- a few seconds later I/O errors
- After rebooting, the root filesystem (ext3) could not be mounted
- After fscking and a lot of deleted inodes, large portions of the
filesystem were gone to lost+found (/etc, /bin, ...)
I can only relate this to the driver, it seems very unstable :(
Some info: 2.4.20-ac2, asus a7v8x motherboard (onboard promise raid not
used), iwill IS150-R raid controler, 2 Maxtor 6Y080M0 SATA disks in
raid1.

I got severe filesystem corruption on an Sii3112 system (Supermicro
E7505 with 2 onboard SiI3112) but I later memtested the machine and
found bad ram, so I dont think it is a valid example of corruption.
However I am still slightly suspicious. Did you have
echo "max_kb_per_request:15" > /proc/ide/hdXX/settings
set for the relevant drives? This is a known bug (I didnt have this
either, another reason why this is not a valid datapoint...)

The memory is stable, no problems in memtest.

These were not set when the error occured. I found this option after the
crash somewhere on the net, but I can't find any references to it on
google at the moment :( Can it cause that severe filesystem corruption ?
Was DMA enabled on your system, and what drives did you use ?
I tested several firmware revisions, disabled mmio in the driver,
nothing helped. No DMA at boot, and the crash is easy to reproduce, for
example:
console1: dd if=/dev/hda of=/dev/null
console2: hdparm -X66 -d1 /dev/hda
result without max_kb_per_request:
---

The system hangs and nothing is written to syslog.
I don't know where to look next.
