Bug Description
I am testing daily build of Ubuntu 10.04.
Couple of days ago I notice that my Lenovo T400 (2767-R9U) some times fails to suspend or hibernate. Today (2010-04-10) after full update I found out this happens only when I have SD card inserted and mounted. I did several tests, but I don't know the root cause of the problem. Here are the test that I did so far:
1. Test suspend when no devices are attached and no SD card inserted. The laptop suspends without any issues.
2. I mounted the second partition and suspended the laptop. No problems.
3. I mounted external USB HDD and suspended the laptop. No problems again.
4. I inserted SD card after the card has been auto-mounted I tested the access. Then I unmounted the SD card and suspended the laptop. No problems at all.
5. I insert the SD card and after confirming access I suspended the laptop. The suspend process starts. The 'suspend LED' flashes. After short time all other LEDs go off except power and battery. At this point everything stops. Usually at this moment the power is turned-off and the suspend LED stops flashing and stays on until the laptop is awaken again.
I have tested this with number of different SD cards from Transcend, San Disk and Kingston, different capacities ranging from 256MB to 8GB and different formats SD and microSD with adapter. It appears that SD card it self is not the problem.
6. I have repeated the same test, but this time the SD card was connected using external SD-USB adapter and suspend worked as expected.
So I am suspecting that the problem is somewhere in the driver. I am attaching the full list of my hardware created by 'lshw' command. From there looks like the SD controller used by Lenovo is:
bus info: pci@0000:15:00.2
What should I do in order to find the problem?
Thank you,
SAL-e

I can confirm this. I am having the exact same problem o a Toshiba M305-S4820 laptop, running Ubuntu Lucid AMD64.
