I am having difficulty with my 20GB LaCie usb harddrive with kernel 2.4.2 on
a Redhat 7.1 system. This drive holds my mp3 collection on a fat32
partition. It works fine under windoze. It works with Linux for a short
time: I can mount the filesystem, traverse it, and play a few mp3s. But
after playing 5 or so mp3s, my kernel will panic and my lacie's drive light
will stay solid green.
I get different behaviour with kernel 2.4.3. The kernel will not panic, but
the userspace process (like xmms or mpg123) will freeze permanently.
Here is my debugging info:
