[linuxsh-dev] Odd problem

[Stuart M. <Stu...@st...>]

Folks

I've been looking at an odd problem for the last few days, and not
getting anywhere fast, so I was just wondering if anybody else has seen
something similar.

I have an IDE disk attached via a PCI card, which used to work fine.
However recently (unfortunatly I don't really know when) I started
seeing a problem:
  hda: lost interrupt
followed by some more debugging information which would appear to
indicate that the command was a disk write. The problem appears to be
unique to writes (mounting the file system read only, everything is fine).

However there are some odd features. For example turning off CPU
caches appears to also fix the problem, and whether disk is the root
file system, or mounted off a root filesystem on a ramdisk also
has an effect, but not conclusivly.

This is using the 'lastest' kernel from SourceForge (updating this
afternoon), but has also been seen in a 2.4.0-test5 system from a few
weeks ago.

Any suggestions welcome (please!)?
