This is on a Dell XPS M1330 laptop with Nvidia GeForce 8400M GS, 8 GB RAM, and 2.6 GHz Core 2 Duo T9500. I'm adding the kernel package to this bug report as it could be a kernel issue. This happens only on Wayland. This issue, however, is not present under Fedora 25 or 26 when running Wayland. **

If the motherboard allows it, disabling the OpCache will completely prevent (or at least greatly reduce the probability of) the ASLR-related crash, even if ASLR is enabled in the kernel. As far as I'm aware it has no effect on the other type of crash. -- You received this bug notification because

This is the DragonFlyBSD commit. https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/b48dd28447fc8ef62fbc963accd301557fd9ac20 It appears that there are two different ways that the system can crash, which is why it is necessary to both disable ASLR and to compile the kernel with CONFIG_RCU_NOC

If any of your RAM timings are odd (eg. 17), setting them to the next even number (eg. 18) helps a lot. Recompiling the kernel with CONFIG_RCU_NOCB_CPU and CONFIG_RCU_NOCB_CPU_ALL, and disabling ASLR is still necessary though. It may also be a good idea to give the SOC slightly more voltage, but no

AMD has not publicly commented on this issue that I'm aware of. This issue has been seen on many different operating systems. DragonFlyBSD includes a workaround for this issue.

Reopening because even though this is a known issue with the CPU we could still implement a workaround. One workaround is to disable address space layout randomization: echo 0 >/proc/sys/kernel/randomize_va_space However, that would be disabling a security feature. ** Changed in: linux (Ubuntu)
