In this case with Precise, was the problem that we were testing Ubuntu's HWE kernels [1], so we missed that the bug existed in their GA kernel (kernel 3.2)? Excluding Ubuntu's HWE situation, I think we'd always want to test against "the newest", right? Users should be running whatever is the newest, for security's sake. - Ken [1] https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Kernel.2FSupport.A12.04.x_Ubuntu_Kernel_Support -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
