Thinkpad X60 Feisty - Suspend issue SOLVED

[alastair]

I have a Thinkpad X60s running Edgy. Suspend and hibernate work well (generally).

Yesterday, I installed Feisty (on a different HDD) and was depressed to
see that suspend FAILS. The laptp suspends OK, but does not resume. It
gives a blank screen and on/off busy cursor every now and then. This would
mean a return to Edgy.

However - I have FIXED suspend (and hibernate also works) by adding
the option "ec_intr=0" to the grub boot stanza i.e.

In file /boot/grub/menu.lst - my boot line now looks like :

# defoptions=quiet splash vga=791 ec_intr=0

This was recommended in the Thinkwiki page :

http://www.thinkwiki.org/wiki/How_to_make_ACPI_work

Many ThinkPads have been hit by a recent (kernel 2.6.16) change to ACPI4Linux that changed the default means of accessing the ACPI Embedded Controller as a way to shake out underlying bugs in the EC access code. If your ThinkPad fails to resume properly (a blinking Sleep light on resume that doesn't go away, or a hang when trying to suspend/standby a second time), adding ec_intr=0 to your kernel command line may help.

I hope this helps someone else.

Thanks. I feel like this is just a band aid and its hurting something else, but it has to be better than "acpi=off" Cheers

Anyone try this on an R40 yet? I'd love to upgrade mine, but suspend just doesn't work.

Didn't help me on my thinkpad x31 either.

This appears to be working on my x60s (to a certain extent).

I've changed two lines

# defoptions=quiet splash vga=791 ec_intr=0

and

kernel          /boot/vmlinuz-2.6.11-1-686 root=/dev/hda1 ro acpi_sleep=s3_bios
