Debugging is my pleasure

Posted on 14-Dec-2004

About a month ago I decided the time had come to find out why, when I attempted to blank a cd in my cd rewriter, cdrecord (the program I was using to do this) hung – and then could not be killed off because the operating system thought it had outstanding I/O in progress.

This meant getting down to a copy of linux source code, building a system with some debug statements in it and finding out what was going on.

It was a hard three weeks, but I have eventually proved that there was a hardware problem with my drive. I must say, it was one of the most satisfying activities I have undertaken recently.
