I have an X220 with the same issue. Using a MicroSDHC card with an adapter. Windows likes it, Linux does not. Very similar looking errors as what Jeremy has. Linux: 3.1 BIOS: 1.21 (08/02/2011) OS: Debian Wheezy SanDisk adapter with Kingston 4GB MicroSDHC card. I could help with any testing. -- "A search of his car uncovered pornography, a homemade sex aid, women's stockings and a Jack Russell terrier." - http://www.dailytelegraph.com.au/news/wacky/indeed/story-e6frev20-1111118083480
