Slow performance during install [SOLVED]

Hi all,

I'm installing Gentoo for the first time in a Table PC (HP Compaq TC4200) through a USB Key and something really wierd is happening. The boot works but is _extremely_ slow hanging for ages in coldplugging (using 2006.0).
Then after it was done (about 45 min. to boot), I get a stage 3 and unpack it. It has been unpacking for almost an hour. I used xvjpf and it uncompresses some files and stops, then uncompresses some more and stops, then some more and stops. This is definitely not what I'm used to. Can it be due to usb key install (I used docache as boot param, so it should not be). Is there a way to make this faster?

Cheers,

Paulo Matos

USB 1.1? If yes, it means slow.
No DMA on the target hard drive? Check via hdparm -i /dev/hda. If yes, it means slow.

Hang on - docache? How much RAM does that system have? If almost all of it is taken by the source media cache, of course it'll be slow as hell

Oh, 2G, it's unlikely to be that.
Don't yell at me for asking, but I have to ask: Are you sure you're decompressing to the file system on the target drive and not to RAM? I've seen attempted installs where the user forgot to mount /mnt/gentoo and was operating on the RAM disk... A quick df -h should tell you.
If it's not that, take a peek at what top says. While uncompressing you should see bzip2 skyrocketing to 99% CPU - if it doesn't, we'll at least know what to rule out.

kacpid is a kernel process, you can't kill it. I'm afraid the only way out is to reboot, this time using the noacpi kernel command line flag.
