Hi
I'm preparing a patche for the dump driver.
So I'm testing it. But when using insmod dump_rle (it is a module to use rle compression while dumping) It panics immediatly, it don't even start the initialisation.

By using insmod -m I have:

Using /lib/modules/2.4.19-pa22/kernel/drivers/dump/dump_rle.o r_info 0x29 not handled
r_info 0x29 not handled
r_info 0x29 not handled
r_info 0x29 not handled

000d3430 r .PARISC.unwind -> PANIC !!!!

Any idea, any suggestion to have more debug ?
Where this .PARISC.unwind comes from ??? It is not in my code.

thanks.

hi
It seems to be a weird problem. I've recompile everything
(make clean && make dep && make vmlinux && make modules && make modules_install) And:
-A-class: 64bits compilation, it panic, but not at the same place than before:

# insmod -m dump_rle
.
.
.
Symbols:
000d3000 D __insmod_dump_rle_O/lib/modules/2.4.19-pa22/kernel/drivers/dump/dump_rle.o_M3DB6A52E_V132115

000d3630 d dump_rle_compression
000d3630 d .data
000d36b0 d .bss -> it panic here

-712: works fine !!!!!

I'll try to install the latest 64 bit compiler....

Hi Bruno,

We seem to be having some general problems with insmod causing random crashes. I would suggest that you stick with building things into the kernel instead of modules for a little while until we figure out the insmod problem.

Thanks.
I've already noted that when building in the kernel it was running fine. About this insmod panic it is a bit strange, because, on the A class, it is completly crashed after that. I have to power off/on.

bye.
