[Users] Kernel stab134.8 - panic at boot

[Vasily Averin]

Dear Corrado,

> Thu Jan 17 14:33:30 CET 2019 Info: Installing ///lib/modules/2.6.32-754.el6.x86_64/extra/arcmsr/arcmsr.ko
This points to out-of-tree driver.  Please call 
rpm -qf /lib/modules/2.6.32-754.el6.x86_64/extra/arcmsr/arcmsr.ko  
to be sure.

I afraid this driver is not included into original RHEL6 kernel, and was compiled/installed separately.
RHEL6 kernel is in maintenance mode, they do not add support for new hardware.
OpenVz6 inherit the state from RHEL6, we have no resources for hardware tesdting/maintenanace.

So you can:
- install out-of-tree driver over our kernel, like you did for original RHEL6 kernel, 
   (and repeat the procedure after each new kernel update)
- or switch to using OpenVz7, that is based on RHEL7 and inherit support for new hardware.
- or install OpenVz6 on old hardware.

Thank you,
	Vasily Averin
