Tiger bit me in the arse
I had a bucketload of problems upgrading my Power Mac G5 to Tiger. I just did a regular upgrade -- I didn't do a clean install, or an archive and install, and that was probably my first and worst mistake. But afterwards, stuff stopped working.
First I noticed some weirdness in my games -- erratic sound problems, or video playback problems (issues, perhaps, with QuickTime 7?). Then I saw a kernel panic. First time that's happened in well over a year, as best as I can remember. The worst came when I tried to transfer a large block of data from my Power Mac to my PowerBook using FireWire target disk mode, however -- it got maybe a quarter of the way through 6GB worth of transfer and then the Power Mac froze up. I got the restart screen and the fans started blowing on high.
I figured after I restarted that the best thing to do would be to simply transfer off most of the data to a DVD-R, so I threw one in and began copying. -36 error. I've burned multitudes of CD-R's and DVD-R's with nary a problem on this machine, but now it's suffering.
Anyway, all this happened prior to my recent trip to Los Angeles. Last week was rather screwed up -- I was down for a day after the trip and started pedaling as fast as I could afterwards, so I really didn't have a lot of time to troubleshoot the problem. Anyway, I've since done an archive and install, so I'm hoping that will help straighten things out.
Until I do, I'm keeping Panther on my PowerBook, which is my daily workhorse. No sense in screwing up an otherwise perfectly reliable system until I figure out what combination of software it is that is making Tiger cough up hairballs.
