Dear Debian, further to my last, I have discovered that my J-542B motherboard has blown a couple of capacitors, perhaps in collusion with a dodgy power supply. I have replaced it with a Soyo EH5H, and the installation proceeded very smoothly. Partman still does not correctly recognize one of my disk's existing Windows partitions, but since I installed to a different disk, this did not prevent the installation.
Prior to replacing my motherboard, I was seeing ever-more-unpredictable behaviour from my system, so I am not convinced a bug actually existed. Thank you, Eric White. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
