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, stijn -- http://hasthelhcdestroyedtheearth.com/
