[parisc-linux] not freeing initmem and power button

[parisc-linux] not freeing initmem and power button

[Kenneth Westelinck]

Hi all,

After a few months of gathering dust, I finally decided to upgrade my 
712/60. It was initially installed with the old 0.9.2 ISO, and upgraded with 
a more recent kernel (I think it was 2.4.9). This weekend I did an apt-get 
update, apt-get upgrade to upgrade my system (woody). I also compiled a new 
kernel (2.4.18-pa16) for this system. The system boots fine and as far as I 
can see, all applications "survived" the upgrade. The only problem I am 
experiencing are 2 _bugs_ mentionned a while ago in the mailing list.

- When booting the kernel reports: NOT FREEING INITMEM. I found this in the 
mailing list, but I couldn't find a solution. Is there any solution for this 
problem? I don't think I had this when running the old kernel.

- Second, when I push the power button, the system powers off without doing 
a clean shutdown. When running the 2.4.9 kernel the machine didn't halt when 
pushing this button. Only typing in "shutdown -h now" did the trick. I 
prefer this behaviour. In this case a normal user cannot shutdown the 
machine, except by pulling the power cord. Can someone please tell me which 
file to edit/tweak to give back this
old behaviour?

Many thanks in advance.


regards,

Kenneth

enjoy life, enjoy linux,

Kenneth

Older kernels just didn't reported it, but all had this problem.
We're not freeing the memory yet, since we still have one or more 
__init or __initdata too much in our kernel. Just ignore it for now.

The power-button should work if you update to a newer kernel (>= 2.4.18-pa19).

Do you recall what config failed when we did try to free the memory?  I
tested recently with B180 and A500, both worked fine with freeing of
memory enabled.  IIRC the origianl problem was that init crashed on
boot...

Cheers,

Hi Richard,

unfortunately I don't know which config it was. AFAIR it also never 
happened to me, but it did for grant or bame. Maybe they know more ?

Greetings,

FYI, I've re-enabled the freeing of boot memory in the CVS version
of kernel 2.4.18-pa20 and am very interested in getting your feedback.
But, since this change _could_ do anything to your system, please don't use 
it if you have important data on your disks (or at least without having 
a backup somewhere).

In case you see any boot-related or other strange problems with this kernel, 
please let me know as soon as possible and remember to attach your .config file.
I've tested this kernel on all my machines and haven't had any problems yet, so
I personally think it's safe to use this kernel. But in any case: You've been warned :-)

Thanks,
Helge

I don't recall offhand. If it's not in the mail archives, my configs
are stored in the tarballs I upload whenever I build kernels specifically
for C3000 (32-bit) or A500 (64-bit). Those tarballs are on
	ftp://ftp.parisc-linux.org/kernels/c3000 or a500
