Investigating 5.3-RC1 panic

• 本文约 1249 字，阅读大致需要 6 分钟 | Development

Before reporting this to the list, I would first gather enough information.

Alu’s server boxes is suffering in continued reboot when server is loaded. Because he is supporting FreeBSD by utilizing 5.3-RC1 in his production environment (and it’s moderately loaded as it is connected to the ChinaNet Backbone), and donated many devices for dedicated services of the FreeBSD China Community, I think we must help him to solve these out.

I have plugged a new kernel configuration on his box in order to obtain a (potential) crashdump and figure out what is happening. Maybe we will get it tomorrow.
