B0087 stmmac: kernel function invoked from invalid context
You can find more information on bug tracking system available at https://redmine.soft-in.com/
1.5. KNOWN BUGS
B0259 ETH: Ethernet connection falls down during transferring files There are also some known issues that are platform dependent (see 1.5.1) and other issues related to upstream kernel (see 1.5.2).
You can find more information on bug tracking system available at https://redmine.soft-in.com/
1.5.1. HW DEPENDENT BUGS Here the list of open bugs:
B0115 Random behavior accessing MMC on CUT2B1 (this bug is closed as HW issue specific to the Micron component used on Abbeville builds prior to Build 4)
B0218 ETH link detected without cable (this issue existed with the cut 1 driver as well, but didn't occur on Northville, only on Crossville's. It seems to be Crossville PHY specific)
1.5.2. UPSTREAM BUG Here the list of upstream bugs:
B0093 Removing USB flash drive during a file transfer might crash the kernel B0097 Problem with usb: scsi: killing requests for dead queue B0117 4 seconds boot slowdown B0166 SATA: kernel oops after surprise removal
1.6. Reference test setup

The kernel has been verified with the Meego 1.2 image meego-ivi-ia32-conx-1.2.0-WRSI-05.27-1.iso replacing the kernel and modules with the binaries compiled with the current release. The kernel command line included the following options: rw root=/dev/sda3 vga=current 3
1.7. Acronyms
PCI Peripheral Component Interconnect
PCIe Peripheral Component Interconnect express
DID PCI Device ID This is the 2 bytes code that identifies a PCI device. Reference available into the site www.pcidatabase.com
2. Format of deliverables
The device drivers are released as Linux patches based on the 2.6.39.4 kernel version. An additional tar file with all changed source files is added in order to facilitate the access to users without a Linux expertise:
The sta2x11_RC4_20120309_2.6.39.4_patches.tgz file contain a snapshot of all the latest STA2X11-CUT2 patches to be applied to Linux kernel version 2.6.39.4.
The sta2x11_RC4_20120309_2.6.39.4_src.tgz file contain all changed files with respect to original Linux kernel version 2.6.39.4.
3. Installation
Let’s have the full kernel 2.6.39.4 into the folder work/linux-2.6.
Extract all the patches from the file sta2x11_xxxxxxxxx_patches.tgz into the folder work/patches
Using the following script you can easily apply them on the top of a clean 2.6.39.4 kernel. Copy it inside kernel source folder
#!/bin/sh for file in `ls $1` do patch -p1 < $1/$file

Execute the script: cd work/ linux-2.6
./patchKernel.sh ../patches
Configure the kernel with the following command:
make sta2x11_defconfig
Compile and install the kernel as usual.
