Hi
!
A few days ago I've
posted a question about kernel panic message "unable to mount root FS on
72:01" in RH 7.3 an Promise Fastrak 100 (20267)
As I am a
beginner in Linux OS maybe I do any so called "stupid mistake" and forget
about setting something ?
I've carefully
followed Murty's howto, step by step and his tips I've found on list
archive. He suggests that the above message means
that append line is
required. I've followed his instruction about finding the correct IRQ and
IO Addres parameters (less /proc/pci)
and I've set it in
append line that way. After doing so the system seems to start the right way, it
finds the disks (IBMs) and everything on the screen
starts to happen
very slowly - the Fastrak driver built into the kernel starts (no matter if it's
kernel 2.4.19 or 2.4.20) and after that
there are several
mixed messages "hda: lost interrupt" and "hdc: lost interrupt" and thats
all.
I've found on the
manufacturer's support site - Intel (drivers and etc) tips for RH 7.2
concerning Promise Fastrak 100 integrated onto the Intel's
SCB2 ATA
motherboard. There is an append line but with absolutely different values than
dicovered with with "less /proc/pci).
When I set the
append line in lilo.conf the way that Intel recommends then very quickly
error message occurs about mounting root on FS 72:01.
There is one more
interesting thing I've noticed (I guess in kernel 2.4.20) - when in the append
line I only declare parameters (found in /proc/pci)
for ide0 and ide1
and no ide2=0 ide3=0 etc. the system on boot process reports found ide2 with IRQ
and IOAddr parameters provided by Intel.
So .. What's going
on ?
To summarize
:
I do make an entry
in fstab
/dev/ataraid/d0p1
/ ext3 default
1 1
I've got an entry in
lilo.conf root=/dev/ataraid/d0p1 and no image
declaration
I set all built into
kernel options for Promise controller when building new kernel (following
Murty's Howto).
Where is a trick ?
Question: should I
or not while doing make menuconfig set an entry in section File systems for ext3
and if so to set up as built in or module ?
I have no SCSI
devices - can (or should) I switch off SCSI support in a new kernel build
while using ataraid ?
And what else should
I pay special attention to and eventually had set ?
Thanks a lot in
advance for any answer .
