PS: linux version shown by dmesg is 2.6.24 but it
is the results of 'git bisect good v2.6.24' and
'git bisect bad v2.6.25'

So what's the changeset hash for the source that produced this
kernel?

root@Calimero:/tmp/GIT/herbert# git bisect good v2.6.24
You need to start by "git bisect start"
Do you want me to do it for you [Y/n]? Y

[dd5f5fed6c9458a7aa81eeef3732cc3a9891cfdf] Merge branch 'audit.b46'
of
git://git.kernel.org/pub/scm/linux/kernel/git/viro/audit-current

Then I have copied from 2.6.25 two files:

net/ipv4/xfrm4_tunnel.c and ipcomp.c because
of these bugs:



http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.24.y.git;a=commit;h=11b47c8828d4cd1df21636719603784ec5e26067

and finally I have run 'make menuconfig' and
'make bzImage modules modules_install'

ok, I have git bisected again:

[fde3571fd8613483f1203d11394ae316c6b79a03] iwlwifi: avoid firmware

and then copied always the two files from 2.6.25
xfrm4_tunnel.c and ipcomp.c

now this kernel is up for 4 hours (at least it
doesn't crash at startup)
I will keep you updated.
Thanks for the feedback Herbert.

NAK: it crashed after 4 hours and few minutes with
this message:
