    hi all,
    (i'm not on the list so please put me in CC when replying.)
    we are using blcr 0.8.2 on sl5.4 x86_64 systems and we are seeing
    strange things with restarting checkpoints taken on kernel version A and
    then restarting it on kernel version B. 
    B is supposed to be a 'security/bug fix only' update of A (from
    2.6.18-164.6.1.el5 to 2.6.18-164.11.1.el5, but who knows what patches
    are in there ;)
    checkpoint/restart works fine on both versions (also the testsuite
    RUN_ME passes all tests), but when restarting a checkpointed job from A
    on B, the machine gives a kernel panic (and i can't find the complete
    panic message  :(
    is there any guideline on the behaviour of restarting on different
    kernels (same BLCR version though, but only the blcr module rpm is
    upgraded, i assume that the other rpms are independent of the kernel).
    is this suposed to work at all times? 
    many thanks,
