You can expect most bugs in 3.2 has been fixed so it's very stable. Old doesn't mean unmaintained. Debian's kernel developer Ben Hutchings has been backporting for 3.2 for a long time with lots of security fixes and hardware enablement. In comparison, RHEL 6 uses 2.6.32 with lots of selected stuff backported. This development model avoids new random features introducing bugs. Also, you can have newer kernels in the debian backports repo.
