I am new to Mint but not to Linux in general. I just installed Mint and attempted the upgrade solution described above (obviously before I read this post) and found myself with the same outcome. I tried reinstalling the VirtualBox "Guest Additions" since I know that it provides some kernel modules and I was afraid this might be causing problems, but alas, it did not solve the issue.
I'm fairly happy not upgrading the kernel very often (especially if I run this on my main machine which requires a recompiled kernel for nVidia drivers); however, can you please tell me the "suggested" way to upgrade Mint and if there are plans in the works for an upgrade path?
Mint seems like a great choice for an OS, but kernel panics every time I actually NEED to update the kernel would really be kind of a pain.
Thanks for your comments/suggestions
