問題点の説明:
PHKL_35795:
(SR:8606460609 CR:JAGag16647)
1.25GB未満のメモリーしか割り当てられていないvParが、ブート時にパニック
になることがよくあります。次のようなメッセージが表示されます。
panic: No equivalently mapped space.
解決方法:
十分な等価マップメモリーがあるか確認するようにコードを修正しました。

PHKL_34915:
( SR:8606431729 CR:JAGaf91171 )
On a machine with virtual partitions(vPars), a global TLB
purge on one of the vPars can cause other vPar to panic
with "Unexpected trap while PSW-Q = 0" or
"data page fault" or "no hit in cell map" HPMCs.
Defect Description:
PHKL_35795:
( SR:8606460609 CR:JAGag16647 )
A vPar with less than 1.25GB of memory allocated to it can
sometime panic with the following message during boot-up.
panic: No equivalently mapped space.
Resolution:
The problem is fixed by making sure there is sufficient
amount of equivalently mapped memory.
PHKL_34915:
( SR:8606431729 CR:JAGaf91171 )
Global TLB purges affects TLB's of all the Virtual
partitions in a Hard partition(nPar), and sometimes may
lead to an HPMC.
Resolution:
The problem is fixed by ensuring that global TLB purges
does not affect other vPars. The fix addresses the
problem arising from global purging of kernel dynamic
data and unloading of DLKM's(Dynamically Loadable Kernel
Modules) which are loaded in the address range between
0 and 64MB.
Enhancement:
No
