Hi, Alan. I'm back and I'm trying to follow your directions to the letter. I turned hotplugging completely, but kept the "echo 4" part. > Yes.

I tried to cut down the logs to what I thought was a safe minimum. If you don't need some of the lines that I'm including this time, please let me know and I'll do exactly what you tell me to do. > Okay, I've got another patch for you to try.

The logs included were generated with kernel 2.6.0 plus the patch that you sent me before. I will upgrade to kernel 2.6.1 if you prefer me to do that (or any other version, if it helps you). BTW, you mentioned that compiling should take only very little time. I am always compiling the kernel from scratch, since I read sometime ago that the dependency system/Makefiles of the kernel could miss some changes in the files. >From your e-mail I see that doing a "make mrproper" before compiling was overkill, right?
