I have recently combined my two GTX660ti cards into one machine on an XFX 750i motherboard and running Arch Linux. I am getting alot of core dumps of the following type:

Any ideas? Never had a problem when cards in separate machines.

This is result of change in new versions of linux kernel. For more details see https://github.com/BOINC/boinc/issues/2120.

Edit: there is workaround for this, you need to pass vsyscall=emulate parameter to kernel during startup. More details are here: https://bbs.archlinux.org/viewtopic.php?pid=1770266#p1770266.

OK thanks, I'll try with the kernel parameter and post my results.
