unfortunately I cannt found useful information in your attach file.
Could you please do following:
1) boot into 022stab044.1 kernel
2) send me /var/log/dmesg file
3) send me /var/log/messages.* files
4) send me initrd images both for 022stab044.1 kernel and for 022stab045.1 kernel
It should give me all the possible information about your problem.
