Snow screen with HP Elitebook 8460p
-
Hello everybody,
I think I can narrow down the problem with the snow on a computer screen. I updated to kernel for the tftpboot, which can be found FOG - Other Information - Kernel Updates. I installed the newest Kernel - 3.2.4 Core (which I had to download, upload and install manually). I hoped that would solve the snow on the one laptop, but no success.
Now I have HP2730p und HP2740p laptops. Both of them as the trouble maker show me the same error message (as displayed in Robbace initial post)[INDENT][I][LEFT][FONT=arial][COLOR=#555555][ 1.259533] Cound not find Carillo Ranch MCH device.[/COLOR][/FONT][/LEFT]

So this seem to confirm that the install ATI Radeon VGA Card in the troublemaking laptop is the problem. Again I will try to use some kernel options.

has any one came up with an answer to the v86d helper problem?

[INDENT]Hello there,
I also have problem with one of my laptops. It has a ATI Mobility Radeon HD 2600 graphics processor Video Card installed and when uploading or deploying an image I am getting the vbe_init () failed with -22.[/INDENT]
[INDENT]The Dell D610 (Intel Graphics) and HP2730p ([LEFT][FONT=verdana][COLOR=#0000ff]Graphics Mobile Intel GMA X4500 HD[/COLOR][/FONT][/LEFT]) are working great. I should get soon a HP2740p and see how that one will work.Any feedback on that problem is most appreciated.
Cheers[/INDENT]

Exact same issue with Dell Optiplex 760 with A02 bios
Note: I had to wind back the bios from A11 down to A02 to even get PXE to work with FOG -
We have a similar problem with an iMac-12,1 (ATI Radeon 6750m/512M) and the 0.31/0.32 kernel [Linux v2.6.39.1]. Switching to the 0.30 [Linux v2.6.37] CORE kernel got the snow issue fixed and it was able to do an image download for some of the partitions, but missed one of the partitions, though we have not managed to watch the error message fast enough to catch what goes wrong with the main Win7 partition.
However, I was wondering if someone could give me hint for compiling a new kernel. I have Linux 2.6.37 kernel source, and fog_0.30/kernel/core.config. I copied core.config to .config in my kernel source tree, and compiled. All goes well (snow-wise), and it uncompresses init.gz, and appears to mount it. However, then it can not execute init and suggests that I use the init= command line. I tried init=/bin/sh and init=/sbin/init but I get the same error. Clearly I am missing some small detail about how the distribution fog kernel binary is generated.
In addition, I wonder if someone could also give a hint as to how to capture the output that Robbace did so I can copy and paste, not meticulously transcribe from the screen (if I can see it, given the snow effect.
)
Thanks very much Fog fans.
