Description of problem:
When booting modprobe reports it can't locate block-major-2
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install RH7.2 on a laptop
Actual Results: At boot and in messages modprobe line gives the error
modprobe: Can't locate block-major-2. It does not appear to affect the running
of the machine.
I have installed rh7.2 on a desktop i586 p200mmx and this error does not occur.
The other machine is a Sharp PX AX10 ultralight laptop p3 500. This error
occurs everytime i boot the machine. It doesn't appear to affect the operation
of linux but i don't know what it is looking for or even what a 'block-major-2'
[This part is not really a bug but assistance would be appreciated]
Also on this laptop, at bootup the kernel detects that it is a Sharp PC-PJ AX
series then disables the APM. The reason it does this is i had trouble with APM
with rh7.1 and details of the machine were asked for so as to disable the APM
on boot. I would like to know if there is a way of getting the kernel to load
the APM since later kernel versions may now work with this machine. I have
tried apm=on with the loader [using GRUB] assuming i did it right
block-major-2 is "/dev/fd0", eg the floppy drive. I suspect your laptop doesn't
have one built in and hence the kernel not being able to find one.... of course
that's harmless unless you actually have a floppy drive :(
apm=on is supposed to be the way to override the dmi data; if it doesn't work
then I'll investigate why.

cut down version of messages log file
Your right, my laptop does not have a built in floppy it has a usb fdd which i
am still trying to workout how to mount. Any ideas:).
I tried the apm=on as a kernel command again as shown in the messages file
attached about line 12. I am not sure if i have done this right since i have not
used grub loader before. I edited the boot details at boot time.
kernel /vmlinuz-2.4.7-10 ro root=/dev/hda5 apm=on
Assuming this is how to pass commands to the kernel, at about line 21 the kernel
detects the machine type as
Sharp PC-PJ/AX machine detected. Disabling APM.
then it disables the APM. When i run apm as a command an error message reports
'No APM support in kernel'
Any help would be appreciated
