Problem

Systems running Tru64 V4.0x on Charon-AXP could fail to boot with "panic (cpu 0): System does not have a console configured" message when upgraded to newer versions of Charon-AXP.

Example:

initializing ...

polling for units on kzpba0, slot 1, bus 0, hose 1 ...

pka0.0.0.1.1 PKA0 Q-Logic/ISP PCI SCSI HBA

... enter console

CHARON-AXP (AlphaServer 4100), Version 4.9 (Build 19402)

P00>>>b dka0

Solution

Boot with genvmunix and update the kernel configuration file as described below:

P00>>>boot dka0 -file genvmunix

Switch to multi-user if necessary by pressing CTRL-D and locate the configuration file (examples given below assume the configuration name is AXP001):

# ls -l /sys/conf/

total 191

-rwxr--r-- 1 bin bin 2095 May 14 2000 #.mrg..param.c

-r--r--r-- 1 bin bin 14319 May 14 2000 .new..param.c

-r--r--r-- 1 bin bin 14319 May 14 2000 .proto..param.c

-rw-r--r-- 1 root system 2069 Jul 12 19:18 AXP001

-r--r--r-- 1 bin bin 3269 May 14 2000 BINARY

-r--r--r-- 1 bin bin 39091 May 14 2000 GENERIC

drwxr-xr-x 2 root system 512 May 14 2000 alpha

lrwxr-xr-x 1 root system 13 Jul 12 19:16 config -> ../bin/config

...

In the example below, given for an AlphaServer 4100, we can see the controller ace0 has an invalid slot number:

# cat /sys/conf/AXP001

...

bus isp0 at pci1 slot 1 vector ispintr

controller scsi0 at isp0 slot 0

bus pci0 at mcbus0 slot 4

bus eisa0 at pci0 slot 1

callout after_c "../bin/mkdata eisa"

controller gpc0 at eisa0 slot 0 vector gpcintr

controller ace0 at eisa0 slot 4 vector aceintr

...

We'll replace then 4 by 8 (correct number for all models) to correct this:

# cat /sys/conf/AXP001

...

controller ace0 at eisa0 slot 8 vector aceintr

...

The kernel can now be rebuilt, replaced and the system can be rebooted:

# doconfig -c AXP001

*** KERNEL CONFIGURATION AND BUILD PROCEDURE ***

Saving /sys/conf/AXP001 as /sys/conf/AXP001.bck

Do you want to edit the configuration file? (y/n) [n]: <press enter>

*** PERFORMING KERNEL BUILD ***

Working....Fri Jul 12 19:33:11 ???? 2019

The new kernel is /sys/AXP001/vmunix

# cp -p /sys/AXP001/vmunix /

# shutdown -r now
