Hi all,
I have an old computer with motherboard ASUS SK8N with AMD Opteron 148 and 4
GiB of DDR400. There is an onboard SATA Promise RAID controller working in IDE
mode (i.e. not as RAID controller) with 2 SATA disks. In order to use all 4
GiB RAM I need to enable the "4G Memory Remapping" option from the BIOS.
However, if I do that I receive the following errors:
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata2.00: failed command: WRITE DMA
[136B blob data]

I don't know if it is a bug in the BIOS or a kernel bug. Here some info (I'll
provide further info, if needed):

It seems like there are some lines missing from this output. Can you
provide the full dmesg output from bootup?
You also might want to check for a BIOS update.

Yes, I can run tests - it is easily reproducible: I just need to start writing
on one of the disks. (sorry for the two messages)
