SIGCANCEL is non-standard signal, it is not documented because this is internal facility for the threading library.

GPU suggestion: gtx 750ti
Hello, I currently run haswell based desktop and am planning to add a second gpu to get decent graphics functional. I am thinking about purchasing nvidia gtx 750ti. can anyone confirm if its supported by drivers and is capable of hardware acceleration? if not, what current day gpu should i look for?

Yes a Nvidia GTX 750ti is supported by the closed source binary driver according to https://www.nvidia.com/download/index.aspx (enter your data and you end up at https://www.nvidia.com/download/driverResults.aspx/90283/en-us). A GTX 750ti is a bit overpowered for light desktop and media usage but based on a dated microarchitecture and lacks hardware support for the upcoming h.265 video codec. Nvidia drops support for old hardware in their driver from time to time and newer chips have a lower idle power consumption for a given peak performance so you might want to look for a GPU with a newer microarchitecture. The GTX950 would be a good fit but the nvidia driver port is not yet up to version 352.41 which adds support for the GTX950. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Re: GPU suggestion: gtx 750ti
makes sense. I am very likely to revert back to haswell when support for it is there and move this card over to one of the other machines. so, based on what you said, for now 950 is not an appropriate choice? is it correct? thx. .

Because there a some new internal changes in the driver and its file and directory structure, the port has to be adopted to these changes. O.

To answer my own question for the archives: The issue is that ezjail-admin is using freebsd-update, and using the HOSTS uname -r value. In this case it was 10.2-STABLE. If I fake it out with: export UNAME_r=10.2-RELEASE it works fine. I've sent a message to the ezjail maintainer with this info. It looks like ezjail needs to fake out freebsd-update when it's dealing with it's jail(s).
