OK, here comes the details.
The machine is an HP laptop (Pavilion 4423EA) with Fujitsu MHT2030AT
IDE hard drive (28615,8MB). IDE controller is "ALi M5229 PCI Bus
Master IDE Controller" from Acer Labs Inc. The system has 1GB of RAM.
The system itself was FreeBSD 6.1-STABLE with GENERIC kernel from the
installation media (so, I haven't compiled anything). No weird kernel
options in use. Hardware should be very generic all in all.
Now I have a 6.0-STABLE with GENERIC kernel back (from the
installation media, no updates, patches, no nothing) and I have
stress-tested the system. I was not able to reproduce file corrutions
with 6.0 even though I tried to replicate all situations excactly like
with 6.1.
I have done upgrading and downgrading by using boot-only CD and
selecting USER installation set for upgrading.
Ops. I did quite a mistake describing my system. So, all along I was
talking about 6.1-RELEASE and 6.0-RELEASE. Not STABLE.
