[3.7-rc8 regression] Buffer I/O error on device sda during boot (attempt to access beyond end of device)

[M Z]

Hello,

booting vanilla  3.7-rc8 kernel on Acer Aspire 1810TZ yields these
errors (I was using 3.6.9-1 and 3.5.5-1 from Debian experimental
before without these errors)

 [    9.265058] attempt to access beyond end of device

Any idea before I hit the bisect route? (should I worry about these errors? :) )


Thanks

This error immediately showed up when testing 3.7-rc8 and is discussed/patched 
already on https://lkml.org/lkml/2012/12/3/497.
