After a lot of time wasted with Dell support this is my current experience:
1) issue only appears when the laptop is powered on battery
2) this issue disappears when Speed Step is disabled in BIOS (which disables
Turbo Boost as well)
3) this issue is mostly visible on i7 620M 2.66 CPUs; much less
Is this issue specific to the nVidia GPU or would the problem I am
having be the same on the Intel graphics card on the e6410 laptop?
What I am seeing is a crash on suspend having an Input/Output error
reported (in the text suspending sequence) and a message of loading the
crash kernel. Nothing el
I think the problems you are encountering are very different. The
problem for which I originally started this bug report was finally
identified as BIOS problem of Dell Latitude E6410 with nVidia GPU and
Core i7 2.66GHz CPU (probably concerns E6510 series with same specs
too) laptops up to A05 BIO
I have observed this same behavior on my HP Mini 311 - with the
2.6.35-22.35 kernel release, I was encountering frequent hangs when
suspending the system. The problem was resolved upon downgrading to the
2.6.35-22.33 package, and I'm now using a kernel from

Update: after more suspend/resume cycles it turned out that Intel Idle
Driver is not to blame. Unless SpeedStep is disabled in BIOS the laptop
does not realiabily resume on battery power. Since SpeedStep is about
P-states rather than C-states; could someone write an experimental patch
which would
