Hello,
After upgrading to kernel 2.6.21-2 (in fact, the
linux-image-2.6.21-2-486_2.6.21-5_i386.deb package from debian
unstable), I performed some new tests, and it happened again.
Please find attached what I got in the logs. What's wrong here? I will
gladly perform any test or action which you may ask to help track the
problem down. Just ask.
Best Regards,
Pierre-Yves Paulus
