[Virtual-pkg-base-maintainers] Bug#839965: base: Imminent reboot on Sun X4140 servers on boot

[Dima Veselov]

Package: base
Severity: normal

Dear Maintainer,

Problem described here concern Debian Linux on Sun X4140 servers only.
I submit bugreport, because I have 2 of them rebooting on almost every boot and don't know how to dig the situation. I wish to help if got some instructions.

>From this side this works like that:

Sun X4140 with Opteron processors, Xen and bridge-utils, serial console. Also this server known to have Nvidia NCP55 chipset with forcedeth driver. If I boot it up - It reboot on words

Bridge firewalling registered.

The only way to pass this point - unplug network in boot time and plug it back after. Additional information about this behaviour:
1. Yesterday server was working fine. After configuring virtual machines and enlarging memory from 8 to 20 Gb it keeps rebooting every time. Same was for other one.
2. Installing debian 8.5.0 via PXE I got same reboots during kernel loading. Current debian installation succeeded.
3. Reboot happens even booting without hypervisor kernel also.
4. Other linuses work well - using these servers with OEL 6 and RHEL 6,7, all with forcedeth drivers.
5. There are several servers rebooting (debian 7 and 8), so this is not a hardware issue.
6. Firewall is off and i am confused about "Bridge firewalling registered".
