Issue 154: Verbose mode triggers ignore cache mode on Lion - Chameleon open source boot loader project.

Reported by Trauma Tron, Aug 21, 2011

Steps to reproduce the problem:

1.Boot a Lion partition with verbose flag (not RAID)

Expected result:

Boot kernel cache file and display verbose kernel log

Actual result:

Chameleon ignores cache and load each extensions one by one before 
loading the kernel... in verbose mode.

UseKernelcache flag did not work with modified kernel
i am using kernel with lapis fix.i put it in Extra folder.
and set UseKernelCache=Yes but every time when booting Chameleon 
load all kext.this problem only occurs with modified kernel.vanilla 
kernel is ok.

jus a little edit:
the chameleon only load kernel cache when kernel placed in root 
partition and named as mach_kernel

Comment 4 by JrCs, Aug 22, 2011

@akbar moradi:
"Vanilla" kernel caches was created from vanilla 
mach_kernel files.
If you want to use another Kernel Cache (not Kernel image), you must 
create one with kextcache command and force using it with: 
UseKernelCache=Yes & Kernel Cache=xxxx in your 
org.chameleon.boot.plist

@Trauma and @@akbar moradi: try to use version r1448 or above to see 
why your KernelCache file isn't used

hi 
i test the latest realase and.its same as before. i dont have 
problem with verbos mode it work if name the kernel as 
mach_kernel.the main problem is that kernel cahceh only load if your 
kernel name must be mach_kernel.
other thing is perfect.i am also try to specify the kernelcahche 
with this
kernel cache=xxxxxxxxxxxxx
but nothing

Comment 9 by JrCs, Aug 25, 2011

You can use UseKernelCache=Yes and Kernel Cache=xxxxxx where xxxxxx 
is the path to your kernel cache that you have created with 
kextcache.
If it doesn't works please post the bdmesg log as attachement.

@akbar moradi can you test against r1461 with UseKernelCache=Y and a 
"Kernel Cache" entry in your org.chameleon.boot.plist ?

thanks:
its work now but i have one problem kextutilty only create kernel 
cache when a mach_kernel exist in root.
i try to update Kernelcache with kextcache command but i don't know 
how to specify kernel name.
i know this is not the problem with chameleon.
thanks

Comment 13 by Cyrus The Great, Aug 27, 2011

thanks JrCS i try your command:
sudo kextcache -system-prelinked-kernel -K /cyrus_kernel
it create kernelcache for my kernel and now work perfect
