[Bug 561251] [NEW] linux-image-2.6.32-20-generic kernel update produces oops at bootup

[John Mark]

Public bug reported:

after installing updated kernel above, I cannot boot into 2 different
laptops - a Lenovo T400 and Lenovo T500. Both produce the same error - a
kernel oops that appears on the terminal screen almost immediately after
starting the boot.

Here are the kernels installed on both machines:

ii  linux-image-2.6.32-2 2.6.32-20.29         Linux kernel image for version 2.6.32 on x86/x86_64


And in both cases, regressing back to 2.6.32-19 was a temporary fix.
