Hi, today I upgraded a HP zx6000 from squeeze to wheezy and ran into a major showstopper. The kernel installed by linux-image-mckinley (linux-image-3.2.0-4-mckinley 3.2.46-1+deb7u1) will not boot on my machine.
The machine has two of the following CPUs in it: family : 31 model : 1 model name : Madison revision : 5 archrev : 0 features : branchlong cpu number : 0 cpu regs : 4 cpu MHz : 1400.000 itc MHz : 1400.000000 By "will not boot" I mean that: 1) immediately after ELILO loads the kernel and initrd I see no messages and the system appears to freeze. 2) after about 60 seconds the diagnostic LEDs on the front panel change to System - blinking, RED and LED 2 - on, RED and the system reboots. According to the manual this is a "System firmware hang or system fault". The system still boots up OK with the squeeze kernel (2.6.32-48squeeze3). Presumably I should report this as a serious / grave bug against the linux-image packages, but before I do that I'd like to get some advice on how I can try and diagnose this, if at all? Is there any way to bring up some kind of "early console" in the kernel to try and get a handle on what might be going wrong? Can this be done using a serial console?
