[gentoo-hardened] hardened-sources-2.6.38-r* problems at the very beginning

["Tóth Attila"]

I gave a try to hardened-sources-2.6.38-r1 and -r2 on my laptop.
Both version get stuck at the very beginning of the boot process:
"
Decompressing Linux... Parsing ELF... done.
Booting the kernel.
"
And that's it. Nothing happens thereafter.
The processor is Pentium M, so a bit outdated. But it should still work
anyways.

In the mean time hardened-sources-2.6.38 works fine on the same system. I
know, that some improvements were introduced because of a sec conf
announcement after this version. I've simply copied over my previous
config.

Anybody else having the same problem or I'm alone?

Regards:
Dw.

I have experienced a similar issue on h-s .38-r1 while the .37 kernel
works. I get past grub screen but I then get a blank screen and the
computer reboot a few seconds later. Due to time constraints I haven't
tried anything to solve it except trying to redo "make oldconfig" with
the .37 config. I didn't see any difference between the configs that,
to my humble knowledge, could cause this.

Thanks guys.  Best to open a bug report regarding these issues.  There
were some serious changes with -r1  and it will be a while before
upstream fixes them.

The bug reports are better because I can then cc upstream on them.  Thanks.

Try to disable CONFIG_PARAVIRT. Seems like it causes the freeze both on
virtualized and real hardware.

CONFIG_PARAVIRT_GUEST, that's it.

Thanks for the idea, but
# CONFIG_PARAVIRT_GUEST is not set
