Hi,
Any ideas why a 2.4 kernel would not work when a 2.2 kernel would?
My old hardware is an Asus MB from 1997 with an SIS chipset,
(non-super) 370 socket, Pentium MMX 166 MHz, 128MB EDO SIMMs.
I thought before I buy brand new hardware that requires a 2.4 kernel,
I should try the 2.4 kernel on my old hardware and get it to know.
First I tried to boot Knoppix directly from CD, but this does not
work, even with the failsafe flavour. It hangs like detailed below.
Then I installed the 568tsc 2.4 kernel into the existing Woody system
on that box, but now it does not boot anymore either (unless of course
I choose the old kernel in lilo menu). Woody worked fine on this box
with the Vanilla 2.2 kernel (and before that with ide-pci flavour, and
so does M$ Win 98 SE).
(I am afraid of installing another kernel because this might replace
my working 'old' kernel with the non-working currently 'new' one.)
Here are the last messages I get from 2.4:
: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
: SIS5513: IDE controller on PCI bus 00 dev 09
; PCI: Assigned IRQ 14 for device 00:01.1
; SIS5513: chipset revision 208

+ insmod: Note: /etc/modules.conf is more recent than
/lib/modules/2.4.18-568tsc/modules.dep
The lines prefixed by ': ' appear with 2.2 and both 2.4 kernels.
The lines prefixed by '; ' appear only with the 2.4 kernels.
The line prefixed by '+ ' appears only with 568tsc, but not Knoppix.
The lines prefixed by '. ' appear only with the 2.2 kernel.
Both 568tsc and Knoppix hang at this point, but 2.2 continues like this:
. hda: Maxtor 91366U4, 13029MB w/2048kB Cache, CHS=1661/255/63
. hdc: WDC AC21600H, 1549MB w/128kB Cache, CHS=3148/16/63
Do these two lines indicate a conflict for IRQ 14?
; PCI: Assigned IRQ 14 for device 00:01.1
[...]
: ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Since the first of these two lines is not output under the 2.2, how
can I tell whether this is different on the working system?
This is what I read from /proc/interrupts:
CPU0
0: 558596 XT-PIC timer
1: 8532 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 1 XT-PIC rtc
9: 37 XT-PIC AM53C974, eth0
12: 22678 XT-PIC PS/2 Mouse
13: 0 XT-PIC fpu
14: 768932 XT-PIC ide0
15: 19 XT-PIC ide1
NMI: 0
In fact, I think the ide is connected via pci.
This is what I get from /proc/pci:

Any more ideas? Why would 2.4 break where 2.2 works?
Thanks,
Marco
