Hello,

I have a brand new Fujitsu-Siemens Celsius W360 pc with a FSC D2587-A1
motherboard. It has a intel q35 chipset. In bios I have the sata
controller in pure AHCI mode (legacy pata disabled). On windows
everthing works fine. So mem is ok, too, tested with memtest+ overnight.
No failures with hdd or motherboard on windows. There's latest avaiable
BIOS version on the machine.

Specific system data see below.

I first tried self compiled kernel 2.6.24-rc3 and now at the end
2.6.23.9 to have a stable version. I got compiled e1000 module for
network card onboard under latest gentoo stable version.

I first got acpi failure on boot, pci=nommconf worked first time, than I
patched with q35.pci.patch from
http://bugs.gentoo.org/show_bug.cgi?id=198810 and boot worked without
nommconf.

It disables PCI BARs during sizing. ISTR Linus opining that this was the
wrong thing to do?

ISTR him having opinions on mmconfig too ;)

We should not require people to use obscure boot options to get their
machines working.

But the effect is under every circumstances described above that I got
after an unspecific time EXT3-fs errors. I tried to use different
partitions, one for root and data, got errors on both.

Dec 3 15:05:34 adira EXT3-fs error (device sdb4): ext3_new_block:
Allocating block in system zone - blocks from 74907667, length 1

I tried different hard disks, different sizes of partitions, always the
same issue. I always saw that mem is fully cached (I have 8GB RAM!).
After that, the ext3 has severe faults fsck.ext3 repaired them, but an
amount of data was lost.

I also tried with different file systems (reiserfs3, xfs), also kernel
trace errors, so I got back to ext3.

Can't believe that it's a pure fs-error. Is it an ahci.c issue? Or a
problem with acpi and memory management?

At a guess I'd say the disk system is being bad. it might be a hardware
failure too - it's a new system.

Any ideas for fixing this?


Nope, sorry.
