Hi all,
I finished some experiments to figure out what is going on
so again
I have udoo board x86 ultra
1) Use ubuntu with vanile kernel 4.10.0-28 or 4.13.0-37 or 4.9.51 no problem
with sd card , all work perfectly
2) Use 4.9.51 with ipipe patch -pipe-core -4.9.51-x86-4.patch guide to
system no responce
when i insert sd-card or insert own rtdm module for gpio test and gpio
interrupt occured
3) I use xenomai from git branch stable-3.0.y (download yesterday)
4) there is options from menuconfig that I enable/disable
* General setup
--> Local version - append to kernel release: -xenomai-3.0.5
--> Timers subsystem
--> High Resolution Timer Support (Enable)
* Xenomai/cobalt
--> Sizes and static limits
--> Number of registry slots (512 --> 4096)
--> Size of system heap (Kb) (512 --> 4096)
--> Size of private heap (Kb) (64 --> 256)
--> Size of shared heap (Kb) (64 --> 256)
--> Maximum number of POSIX timers per process (128 --> 512)
--> Drivers
--> RTnet
--> RTnet, TCP/IP socket interface (Enable)
--> Drivers
--> New intel(R) PRO/1000 PCIe (Enable)
--> Realtek 8169 (Enable)
--> Loopback (Enable)
--> Add-Ons
--> Real-Time Capturing Support (Enable)
* Power management and ACPI options
--> CPU Frequency scaling
--> CPU Frequency scaling (Disable)
--> ACPI (Advanced Configuration and Power Interface) Support
--> Processor (Disable)
--> CPU Idle
--> CPU idle PM support (Disable)
* Pocessor type and features
--> Enable maximum number of SMP processors and NUMA nodes (Disable)
--> Processor family
--> Core 2/newer Xeon (if "cat /proc/cpuinfo | grep family" returns 6,
set as Generic otherwise)
--> Transparent Hugepage Support (Disable)
--> Allow for memory compaction (Disable)
--> Contiguous Memory Allocation (Disable)
--> Allow for memory compaction
--> Page Migration (Disable)
* Device Drivers
--> Staging drivers
--> Unisys SPAR driver support
--> Unisys visorbus driver (Disable)
I consider, that something wrong with this options
Help please to start work with xenomai
С уважением и надеждой на сотрудничество,

Can't reproduce this one (over kvm), 4.4 and 4.9 included, so this may
be depending on the Kconfig.
