Issue #2971 has been updated by liweitianux. Status changed from Feedback to Resolved
peeter, thank you for providing more information on this issue. By the way, I've been running DragonFly BSD with HAMMER1 on an old machine for the last ~2 years, and never see such an issue or similar ones. Also, DragonFly BSD has undergone various major changes since then, so this issue is somewhat irrelevant. Let's close it now. Cheers, Aly ---------------------------------------- Bug #2971: kernel 4.7: buildworld causes panic: Bad link elm 0xffffffe1c766d500 prev->next != elm http://bugs.dragonflybsd.org/issues/2971#change-13735 * Author: peeter * Status: Resolved * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- The panic happened while doing buildworld. I am not entirely sure that the panic is not caused by a hardware error since prior to the panic two CRC errors showed up in /var/log/messages. On the other hand, it seems they might not be caused by a hardware error since prior to the panic I had seen CRC errors a couple of times and reinstalling the system got rid of them. In more detail, the machine has gone the following cycle of couple of times: 1 - system has a panic (related to the kernel module I'm developing) 2 - hammer checkmap starts reporting errors occasionally 3 - then CRC errors show up /var/log/messages 4 - re-install the system and all errors vanish 5 - go back to 1 However, the last time after step 3 "make buildworld" led to this panic. ---Files-------------------------------- hammer-crc-error-crash.txt (9.48 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
