Support Notes for SUSE LINUX Enterprise Server 10 Service Pack 4 for HP Integrity Servers (5900-0402)

18. When Linux boots on an mid-range/high-end (cellular) IA-64 machine with discontiguous
memory, a cell may end up in a state where it has too little contiguous memory available,
and could cause an MCA.
If you experience this issue, try one of the following methods to resolve the problem:
a. Try changing the memory configuration so that the memory in each cell is equal.
b. Try changing the CLM (Cell Local Memory) setting to increase the size of contiguous
memory.
If the system was working previously, try the pdt command at the EFI prompt. If there are
PDT entries, consider replacing the bad memory.
19. The Kernel Debugger (KDB) is included in SLES 10. When a Transfer of Control (TOC) is
issued, instead of producing a dump, the SLES 10 kernel enters the KDB. This process may
cause issues, and HP recommends that you do not use TOC.
20. This problem is specific to the LSI1068 SAS I/O controller in the rx2660, BL860c and the
BL870c.
The mpt driver included in SLES10 SP4 does not have the necessary agent components
required by HP System Insight Manager. To fix this problem, HP has qualified a special
version of the mpt driver, which can be downloaded from the drivers area of www.hp.com.
