Hi,
Christian can't get s2ram to work to work with a 2.6.17 kernel, although
it is in the whitelist. It used to work with 2.6.16. Do you now of any
regressions?
Could anybody give him a hand in trying to get it to work again?
In the mean time I asked him to try with minimal number modules loaded.
Thanks,
Tim

Subject: Does not properly exit sleep mode with kernel 2.6.17
When used on my laptop with kernel 2.6.17, s2ram never properly exits
sleep mode while it works well with 2.6.16 kernels (both are stock
Debian kernels: linux-image-2.6.16-2-686 version 2.6.16-17 and
linux-image-2.6.17-1-686 version 2.6.17-5).
[EMAIL PROTECTED]:~> s2ram -n
Machine matched entry 88:
sys_vendor = 'Dell Inc.'
sys_product = 'Latitude X1*'
sys_version = ''
bios_version = ''
Fixes: 0x2c VBE_SAVE VBE_POST
Machine is in the whitelist but perhaps using vbetool unnecessarily.
Please try to find minimal options.
This machine can be identified by:
sys_vendor = "Dell Inc."
sys_product = "Latitude X1 "
sys_version = ""
bios_version = "A03"
See http://en.opensuse.org/S2ram for details.

I finally have been able to check this. The machine is really locked
down. No more accessible by network and screen is black.
OK, I narrowed the problem a little. Even though I don't know whether
the machine is still alive because I can't try ssh'ing to it right now
(being in a plane....), I can confirm that the screen just stays
black. No matter, indeed, whether I launch s2ram from X or from a
virtual console.
Doing the very same with a 2.6.16 kernel gives a quite classical
result: the screen flashes slightly (probably the VBESAVE stuff), then
comes back to life with minimal backlight-->I indeed have to use the
screen light key of the laptop to bring it to life....
With 2.6.17, this "flash" never happens and the screen just sits
there, completely black.

I tried unloading all the ieee1394 stuff and as much USB stuff as
possible but it didn't give much results.
lsmod output (before any unloading):
