Is anybody else having problems with SDHC cards on Beagleboard?
I have been trying to bring up a Beagleboard as a development platform for a project at work, but I am having a killer problem: any significant access of the memory card (a class 8 SDHC 8G card) will die with a transfer error, followed by about 10 failed sector accesses, followed by the system dying.
I've tried 2 different Beagleboards and 3 different cards by 2 different manufacturers, and the problem is repeatable on all permutations. I've put the cards into a card reader on my workstation and done a "dd if=/dev/sdf of=/dev/null" to verify the cards aren't wedged.
I've searched for this on Google and found no references, but I cannot believe I'm the only person seeing this - but am I?

[sp] I am using a Sandisk 4Gb card. Haven't seen any problems. But, kernel is few weeks old.

For me both 2 GB microSD and 8 GB class 4 microSDHC cards are working fine. E.g. no problems with these commands:
dd if=/dev/zero of=foo bs=1M count=500
dd if=foo of=/dev/null
My linux-omap head is
commit 45e5c5ffd32ade5a21a5e87b4040072590ec3ae1

Merge current mainline tree into linux-omap tree
And kernel is built with "make omap3_beagle_defconfig".
