In what LSP of the 1.2 CDK? Mark has been predominantly discussing the 8240/755 Sandpoint and providing pointers to software that doesn't represent integration of the 8xx software on the CDK. Is this a problem in one of the MPC8xx LSPs of the CDK? > ...meaning that they will clobber an unrelated value in memory 8 bytes > after cpu6_bug. I'm travelling and don't have an 8xx LSP handy, but there was supposed to be sufficient space allocated here to prevent this condition. Thanks for the note and I will check the software to ensure this is correct in the MPC8xx CDKs. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
