I'm going to assign this bug to the Ubuntu Kernel Team as according to
https://wiki.ubuntu.com/KernelTeamBugPolicies
I've been able to determine that the problem with resume is on account
of 'some' device driver, that effects the SATA controller, not waking up
after going into S3 (suspend to RAM)

HP Pavilion dv5: ATA exception on resume from suspend
I was having the same problem (this error: irq_stat 0x0040,
connection status changed) when waking up from suspend, and I'd like to
confirm that updating the BIOS to F21 solves the problem and everything
is fully functional afterwards. Unfortunately, it is in a dv7-1080es.

HP Pavilion
I ran a test suspend on booting that I read about in the kernel
documentation and got a curious result.
I added test_suspend=mem to the kernel boot time parameters (in grub)
and my laptop did the following:
* Blanked the display
* Let out a series of system beeps
* Continued to boot AFTER I hit
HP support's response to me was that they don't support linux on
Pavilions, period, so I'm not sure how likely it is that this will be
fixed by them other than accidentally.
Also, my dv5 is probably going back to HP for other reasons, so I won't
be able to follow up further.

My model: HP DV5-1130EF
I like to point out this link
http://hardware4linux.info/computers/sysinfo/3637/ to let anyone interested
have some details of my hardware configuration.
But in addition, you can look at my lspci-vvnn in attachment
The error messages I have noticed are almost the same
Hello,
I'm using a HP DV5 1073ez and I have exactly the same the same problem.
ata1: irq_stat 0x0040, connection status changed
ata1: SError: {DevExch}
ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000 action 0xe frozen.
And i also think that it is better to correct the bug in the kernel
Hello,
I have also the problem with HP Pavilion DV5t-1000. As neub, I think the
kernel should be fixed there.
