Hi,

Hi,

I'm using the latest Debian 2.6.25-rc7 kernel [0] and I have big troubles
with hibernation. With this version, the hibernation (suspend on disk) is
sometimes not resuming correctly. The only thing I get is a blinking
cursor at the top-left of the screen. The problem is that it is not
easily reproducible : sometimes it works, sometimes not.

AFAIK, 2.6.24 is not affected, but 2.6.25-rc6 and -rc7 (at least) are.

I'm using a Dell Latitude D630. (lspci attached).

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?

Thanks,
Rafael

Hi.

It did not help. I had to test 4 hibernation/resume cycles to see the resume
fail.

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 ?

Regards,

Didier
