Leann,
First of all, thank you so much for you attention to this issue.
Not sure if this is what you wanted, but ...
I manually downloaded and installed (via dpkg -i) the package
linux-image-2.6.27-1-generic_2.6.27-1.2_amd64.deb onto my Hardy system and
rebooted.
Frankly, I can't tell if this bug is present; with 2.6.27-1-generic,
resume from suspend *never* works, regardless of what I do with the
dock. Whenever I attempt to resume, the system powers up, the screen
flickers a tiny bit, and after 4 seconds or so, it reboots.
Looks like a new bug report is in order. But I'm guessing I should
install and test Intrepid first.

To answer another question: this bug does *not* appear in vanilla
2.6.26.3. It also does not appear in vanilla 2.6.24.
To make things easier to people to get up to speed with this bug, I have
updated the bug description.
** Description changed:
A summary of the discussion so far (as of 2008/08/29):
Steps to reproduce:
1) Boot up Ubuntu while the laptop is attached to the dock.
2) Connect a USB device to a port *on the dock*.
3) Suspend-to-Ram.
4) Resume.
Result:
On resume, the hardware powers up (fans, HD, etc.), but software soon locks
up hard. The screen remains black, the system is unresponsive to the keyboard,
ssh doesn't work, and even the magic sysrq keys do nothing.
This behavior has been observed on these systems:
- IBM T60p (ATI FireGL v5200) with an IBM Advanced Mini-Dock, running i386
Hardy. (Reported by DaveAbrahams)
- Lenovo R61 7733A82 (Intel graphics) with a ThinkPad Essential Port
Replicator, running amd64 Hardy. (Reported by Daniel Gnoutcheff)
The problem has been observed with these kernels:
- 2.6.24-{16,17,18,19}-generic
These kernels do *not* have the problem:
+ - 2.6.22-*-generic (i.e. Gutsy's kernels)
- Vanilla 2.6.26.3
- Vanilla 2.6.24
David Alexis is reporting a problem that may be a variant of this bug:
he has found that if he has a USB hub plugged into the system on
suspend-to-RAM, USB is unusable on resume.
The original problem report follows:
uname -a => Linux mcbain 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42
UTC 2008 i686 GNU/Linux
This is Hardy as installed from the 4/16 daily build alternate CD. I
have not installed any updates yet. I have not installed fglrx.
I have made only the following configuration changes, in /etc/default
/acpi-support:
POST_VIDEO=false
SAVE_VBE_STATE=false
Hardware: IBM T60p (ATI FireGL v5200), IBM Advanced Mini-Dock
Procedure for reproducing this bug: plug any USB device into a port *on
the dock*. Suspend-to-RAM. Attempt to resume. The process freezes,
presumably where it is trying to resume the device plugged into the
dock.
The bug does not occur when devices are plugged directly into the
laptop, even when it is docked. The bug does not occur if devices have
been used in the dock ports, as long as they are all unplugged by the
time resume is initiated.
Standard logs attached. Please ask if you need more.
