problems with mtp , better to make a command-line option to can switch off mtp device search on booting

[werner]

I get yesterday an acer laptop with big problems to 
install Linux

booting stopped with error messages like:

physmap_flash.0 failed claim ressource 0

L440GX flash mapping failed to find PIIX4 ISA bridge, 
cannot continue

Then the computer stopped, but not crashed, the cursor 
stopped to blink, but reboot
with CTRL-ALT-DEL didn't work, one had to press the reboot 
button

I recompiled the kernel with all MTP things switched off, 
and that booted.

However, normally it should be compiled everything in the 
kernel, and the kernel
during booting should manage it to see and to use what is 
existent in the computer
of the user, without to stick or to crash.

Probably that is an error already sine time in the kernel, 
not a recent regression.

Better to make a command-line option to can switch off mtp 
device search on booting

So I still think you're crazy to compile in MTD support at all, but
hey, I do agree that it is supposed to work.

The "L440GX flash mapping failed" message isn't new, and I doubt that
that particular driver is the problem. Can you try to narrow it down
to _which_ MTD driver causes problems? Enable MTD again, and try to
enable about half the devices to "bisect" the issue.

3.0 version number: good to make links ; linux utils: correct fdisk, rdev

[werner]

I read people have problems with the 3.0 vs. 3.0.0 kernel 
version.

I also think that the version of the package and 
internelly that of the kernel should be equal.

However, that's not a real problem. It's suficient to make 
just links. With this, everything works completely normal, 
also depmod etc.  , since 3.0-rc1

Although this is trivial, because of the big discusion 
about this, one should tell this the people.  Simply put 
in the kernel slackbuild script, to make such links, 
always if the package / source .bz2 number is diferent to 
the version number in makefile.    Also in the kernel 
source makefile should be included to make auch links 
automatically always if the package and kernel version 
numbers are different.

What however seems to be removed from the linux kernel 
tools, is rdev .  That should be put back, because that's 
important, specially for building distro kernels,  to put 
in vmlinuz the bootdev to 0x80 and videomod 0 as default 
(and also for the installer on the user's computer, which 
adapt it to the user's computer)

There is a next problem that recent versions of fdisk 
starts only with sector 2048 for the 1st partition. This 
gives problems, because some systems needs to start with 
sector 63 or 129. This also should be return as it was.
