[STAGING] Freeze on suspend if SD card is mounted with Acer Extensa 5630Z

[Wolfgang Kufner]

I first noticed this bug with lucid 20100113 (aka lucid alpha-2) iso loopback booted from hd via grub2.
lspci -nn:
0d:06.2 SD Host controller [0805]: O2 Micro, Inc. Integrated MMC/SD Controller [1217:7120] (rev 02)

happened 3 times out of 3 on acer extensa 5630z
did not happen 3 out of 3 on extensa 5635z with same SD card.

tried also:
suspend by lid close with card in but unmounted. works fine.
suspend via suspend in the menu. freeze, the same as lid close.
tried 3 times to suspend (via menu) the same hardware with the same card mounted under installed karmic. worked fine every time.

All the above was done with lucid 20100113 on 2010-01-15.
Today I checked again and the bug is still present.
(I first commented on that bug in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/477106/comments/3.)
