Hi all,
I suspect all the SIG4 and SIG11 problems we see are due
memory corruption in CURRENT.
In the latter case, the affected file looks like:
case HASH('^', 'e'):
case HASH('^', 'i'):
case HASH('^' 'o'):
\xc0 case HASH('^', 'u'):
%case HADH('`', \xc0A'):
^@ase HASH('`', 'E

The file is correct after a reboot, so the corruption was limited to the
copy cached in RAM.
Thats memory corruption. I'm also not able anymore

Hi Soeren,
However, this kind of problem in most cases spells bad HW to me,
ie subspec RAM, poor powersupply, badly cooled CPU, overclocking etc etc...
That's what I thought too. I have now three different systems which show
all this:
1) PIV 1,6Ghz, Intel B845DG Board, 1GB Kingston Ram,
2)

Bye the way, I'm experiencing this since about 4-5 months.

Hi Martin,
As you know this problem for longer, did you already try to make the
problem a bit more reproducable / narrowed down?
If not, we really should try to, that will be the first step in fixing it.

When I first put this system together several months ago, I only
installed the first 512M of RAM and the problem was much worse. I only
had about a 50% chance

When I'm done with that, I'll reduce the RAM from 1G to 512M and try
again. I'll also try the DISABLE_PSE and DISABLE_PG_G options.

We would enable PSE and switch the pde corresponding to the
