Attached are a 2.6.25-rc7 and a 2.6.24 dmesg's after two
successful hibernate/resume cycles.

Could you please check if the problem is still present if you
boot with acpi_new_pts_ordering kernel command line argument?

By the way, I just added acp_new_pts_ordering at the end of the
Grub line beginning by "linux (hd0,1)/vmlinuz(...)". Is that
correct ?

seems strange you should add it to the kopt line and then kick as
root update-grub

# kopt=root=/dev/sda1 ro
it should land
kernel /boot/vmlinuz-2.6.25-rc7-amd64 root=/dev/sda1 ro

Well... I'm using Grub2 (grub-pc). I altered the boot option at boot
time but forgot to check /proc/cmdline. Will try again and report
back.

Hi,

I tried again and ensured that /proc/cmdline 's end was
acpi_new_pts_ordering . It did work for 2-3 hibernation, but then
failed.

Well, there were quite a lot of suspend-related changes between 2.6.24
and now.

Hmm, do you have CONFIG_USB_SUSPEND set in .config by chance?

Rafael

I do (Debian default option)... I will build a kernel without it and retry.

Didier

Hi again.

I compiled the same kernel with CONFIG_USB_SUSPEND not set. After 6
hibernations, I haven't had a problem for now.

Regards,

Didier
