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.
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
and send the output to email@example.com with the subject
This defect is considered SHOULD-FIX for Fairfax.
putting reboot=b or reboot=bios on the kernel line in grub.conf does not fix
The "reboot=b" fixes this problem.
Sent output from dmidecode.c to firstname.lastname@example.org
Fixed in next build
Is this fix for all processor speeds, or just the 800 MHz? We need it for all...
Uhm I assume the "800" in the output is variable then.... ok will fix thanks for
The Power Edge 300 needs the reboot=smp or reboot=smb,bios passed in order to
make it reboot consistently.
What kernel version ?
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
If it doesn't pick it up, or gets it wrong I'd like dmidecode output
so I can fix it asap
Changed to smp,bios just to be safe
