command not found after RH 7.2 kernel upgrade via "Upgrade Agent"

command not found after RH 7.2 kernel upgrade via "Upgrade Agent"

I upgraded the kernel of my Redhat 7.2 (on intel machine) from 2.4.7-10smp to
2.3.9-31smp via the Upgrade Agent (a Gnome GUI tool) sevral days ago. I am not
very sure whether I reboot the system after upgrade.  Now during the shutdown/boot up
time, lots of service and commands are shown as "not found".  I don't how to catch
the screen when system boots up. Is there any way to cahtch it besides using VMware
to boot from another OS?

However, I noticed the following from output of `dmesg`.

u10k1: EMU10K1 rev 8 model 0x8040 found, IO at 0xc400-0xc41f, IRQ 19
APIC error on CPU1: 00(08)
APIC error on CPU0: 00(04)
APIC error on CPU1: 08(08)
APIC error on CPU1: 08(08)
APIC error on CPU0: 04(02)
 ... ... (skip)
APIC error on CPU0: 02(02)
APIC error on CPU0: 02(02)
APIC error on CPU1: 08(04
----------End of `dmesg` ------------

Moreover, the `ifdown` and `ifup` give some error message though it is still functional.

/sbin/ifdown: : command not found

/sbin/ifup: : command not found
Determining IP information for eth0... done.
/etc/sysconfig/network-scripts/ifup-routes: : command not found


/sbin/ifup: Bourne-Again shell script text executable

Is there something wrong with the linking of those scripts?

I would have another general questions about Linux. My system is with dual Celeron 466 and
384M memory. The terminal screen refreshes very slow when doing a ls on the directory with
lots of files in it (say, more than 500), it is so even after I press a space and return.
It is back to normal after I clear the screen.

It happens when ~350M out of 384M RAM are allocated, where 200M are cached.   I guess the
low memory may cause the problem, but why does this happen? After boot up into gnome, only
~100M are used.  It seems something eats up the memory. However, I only run xmms, usernet,
xosview, netscape and terminal those days.

I would appreciate if anyone could give me any pointer.

1. RH 5.2 kernel upgrade "Kernel Panic: no init found"

I am upgrading my Redhat tp Kernel 2.2.13, I followed all the
directions from
2.2/kernel2.2-upgrade.html#toc5 and all works just fine until reboot

When it boots the new kernel it gets to mounting all the devices, then
mounting the root filesystem read only, then the message:

Kernel panic: No init found. Try passing init= option to kernel.

I read through all sorts of other posting about this message, but no
suggestion of init=/bin/sh or init=5 helps.
