Andy, FYI I'm emailing you @visopsys.org with the (zipped) Kernel.log from that session on the old Dell.
Apparently the PM system on this board does not allow attachments (or I couldn't find the option...) .
CU later, cheers
Edit : resent as plain text, reason: your receiving email server does not like zipped attachments. Have you received it now ?
