Description John A. Hull 2001-07-23 16:44:40 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0; DigExt)

Description of problem:
Upon init 6 and "reboot" commands on a console or in Xwindows, the system 
hangs at the console on "rebooting system" instead of resetting the 
power.  All services are reporting to be shut down before hanging, and it 
takes a very long time to see any services being shut down.

System is a Dell PowerEdge 300 with 2 processors and 128 MB of RAM. Occurs 
on SMP kernel only.

How reproducible:

Steps to Reproduce:
1. Load Fairfax beta 2 on a PowerEdge 300
2. Give an "init 6" or "reboot" command
3. System shuts down all services but hangs at "rebooting system" instead 
of resetting power.

Actual Results:  System will not reset power

Expected Results:  System power should reset.

Does passing "reboot=b" to the lilo/grub commandline help?
If so, could you please run the 
http://people.redhat.com/arjanv/dmidecode.c program
and send the output to hardwarebugs-list@redhat.com with the subject
"needs reboot=b"
Comment 2 Glen Foster 2001-07-23 17:18:23 EDT
This defect is considered SHOULD-FIX for Fairfax.
Comment 3 Joshua Giles 2001-07-24 15:41:04 EDT
putting reboot=b or reboot=bios on the kernel line in grub.conf does not fix
this problem.
Comment 4 Joshua Giles 2001-08-01 17:57:36 EDT
The "reboot=b" fixes this problem.
Sent output from dmidecode.c to hardwarebugs-list@redhat.com
Comment 5 Arjan van de Ven 2001-08-02 13:48:10 EDT
Fixed in next build
Comment 6 John A. Hull 2001-08-02 18:22:55 EDT
Is this fix for all processor speeds, or just the 800 MHz? We need it for all...
Comment 7 Arjan van de Ven 2001-08-03 05:17:31 EDT
Uhm I assume the "800" in the output is variable then.... ok will fix thanks for
the warning.
Comment 8 Joshua Giles 2001-08-31 14:58:32 EDT
The Power Edge 300 needs the reboot=smp or reboot=smb,bios passed in order to 
make it reboot consistently.
Comment 9 Arjan van de Ven 2001-08-31 15:04:37 EDT
What kernel version ?
Comment 10 Matt Domsch 2001-08-31 15:37:11 EDT
Josh, it automatically should pick up 'reboot=bios'.  Does it always 
need 'reboot=bios,smp' instead?  (looking at 2.4.7-2.19 now)
dmesg should show it detecting the PE300 and reporting it's going to always do 
BIOS reboots.
Comment 11 Arjan van de Ven 2001-08-31 15:48:37 EDT
If it doesn't pick it up, or gets it wrong I'd like dmidecode output
so I can fix it asap
Comment 12 Arjan van de Ven 2001-09-03 13:40:32 EDT
Changed to smp,bios just to be safe
