Tried running some tasks after upgrading nvidia-kernel-dkms to the 384.90 driver. All the CUDA55 tasks failed. Seti CUDA80 tasks work fine on it.

Link to one of the failing tasks: result 173016915

The 384.111 driver seems to work, so I think we can safely say it’s something in the older driver.

Due to a bug in the BOINC client it truncates the CUDA minor version number to two digits so it appears as 384.11. I reported it on the BOINC mailing lists when the driver came out.
