386 boot problems with 2.4.7 and 2.4.7-ac9

[Carl-Johan Kjellander]

I have an old 386 which ran 2.4.3 just fine. Last night i tried
to upgrade it but it didnt work at all.

I compiled a stock 2.4.7, and since I had seen some postings on
that egcs-2.91.66 didn't compile 2.4.7 I switched to gcc-2.96-85.
The only thing I added to the kernel was ISAPNP support.

The 2.4.7 kernel seems to boot fine, no error messages or nothing,
but it won't start init. The last line is:

   Freeing unused kernel memory: 52K freed

And then it just stops. The kernel is still resonsive but init won't
start. Shift-PageUp still works. SysRQ shows that the EIP almost
always is on the same spot in schedule. I tried init=/bin/sh but
the boot stops at the same place every time.

Then I tried 2.4.7-ac9, same configuration, but that kernel panics.

Relevant parts from System.map are:
c0105000 t rest_init
c0105000 T _stext
c0105000 T stext

c0105038 t init

c010544c T kernel_thread

c01eb7cc t sbf_init

The system is a 386DX with an Award 3.15c BIOS. The distribution
is smalllinux i think, but I've modified it a lot.

Please CC replies to me.
