I don't know what the problem was. With the slow installer I never got
as far as running the system, though. God it was *slow*!

I have tried to install the AMD 64 version of Sarge twice on this
machine. Both times it has been so slow I've given up and installed the
32 bit version of Sarge. I just did, or should say attempted, an 64 bit
install today. It took 55 minutes to do a base install from a
netinstall cd, 10 minutes of which it spent on just loading the
kernel-image package. I can complete a default 32 bit Sarge desktop
install in approximately the same amount of time.
I started my install at 11:15 this morning, it is now 12:59, and the
system is just now unpacking the downloads for a default desktop
install. That's 1 3/4 hours and it hasn't even begun setting up
packages yet. This install will probably take at least 3 hours to
complete, if not more.
Anyone know why this is so slow? I would have completed the same
default desktop bit install an hour ago on this machine if I had
installed the 32 bit version of Sarge. Running 32 bit sarge or sid this
laptop is every bit the equal of my 32 bit desktop machines of similar
cpu speed even though it only has 4200 rpm hard drives and my desktops
have 7200 rpm hard drives.
The 64 bit version of Debian makes this thing crawl. It takes at least
8 - 10 seconds to open Firefox. The 32 bit install opens Firefox in
less than 1/2 the time.
Maybe the 64 bit install has a problem with DMA; that can cost you a
factor 10 in harddrive access times. You can check this with "hdparm".
I tried etch the first time I tried a pure 64 bit installation. I
didn't have any better luck with it than I did with sarge. Glad to
know it isn't just my machine that has problems with this though. Just
out of curiosity, what kernel did you use that worked?
The one in Len Sorenson's netinstall disk.

Thanks. I appreciate the pointer to it. I'll give it a look.
