 Posted: Mon Jun 07, 2004 2:33 pm Post subject: amd64 Laptop cpufreq change causes crash |
 |
|
I have been trying to get my Time Platina 3000 amd64 laptop to use cpu frequency scaling without much luck. It all appears to be setup okay but changing the governor or even the frequency directly causes the laptop to seize completely. The fan also kicks into gear which suggests it is locking at 100% cpu usage. Obviously nothing like powernowd works as they crash the laptop almost instantly.
Using kernel 2.6.5 r1with the powersave and cpufreq as modules. Though I have tried them in the kernel too with the exact same results. I can provide dmesg output if you like (not at the laptop at the moment) but from what I have read on other threads it seems to be fine.
My research has me pretty sure that the Time amd64 laptops are the same as the Voodoo PC ones. Its a shame as other than this the laptop has been brilliant. Any help would be appreciated. As would the name of the the Taiwanese manufacturer which I found once but have forgotten and can no longer find.

1.) Please re-test 2.6.7-rc2 with CONFIG_ACPI_PROCESSOR set to "y"
in arch/i386/kernel/cpu/cpufreq/powernow-k8.c after the line | Code: | | #define VERSION 1.00.9b |
(version number may vary) but before the line | Code: | | #include "powernow-k8.h" |
as seen after loading the module
Thanks. |

I cannot get a bootable 2.6.7-rc2 kernel and I have been trying all day. Various automatic resets and screen blanks during boot have forced me back to 2.6.5-r1
dmesg output on 2.6.5-r1 for the powernow stuff is:
| Code: | powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.20.08b - March 20, 2004)
powernow-k8: 0 : fid a (1800 MHz), vid 2 (1500 mV)
powernow-k8: 1 : fid 8 (1600 MHz), vid 6 (1400 mV)
powernow-k8: 2 : fid 0 (800 MHz), vid 12 (1100 mV)
|
Any other ideas or how I can get 2.6.7-rc2 to work.
[Edit]
Incidently I just tried using powernowd again and it seemed to work OK until it tried to set the cpu speed back down to 800mhz. At which point the laptop locked up.

Can you add
| Code: |
dmesg |grep ACPI
dmesg |grep acpi
|
Is acpi working? Can you read battery status or temperature?
Try this command:
I had to dissassemble and recompile my DSDT table to get ACPI working. At first, battery status where not shown. And dmesg were full of errors related to that.

Yup I can see battery status and acpi seems to be working. Its version 0.06 according to acpi -v. But using anything like suspend causes the laptop to crash bigtime.

powernowd doesn't work also for me by that reason I use cpufreqd with powernow which works nicely.
I also hang my notebook when suspending. Well it suspends ok but gets hanged when resuming back. Then i have to power off manually.
I have tried stopping almost every service before suspending but results are the same. I read in some forums that it could be useful also to compile many of the kernel support as modules to remove them from memory before suspending. Some people got luck doing that. But i haven't tested it.

Sorry, no idea on how to get 2.6.7-rc2 to work; wrt powernow the best thing might be to contact Paul Devriendt, the author of the driver. His e-mail address is noted in arch/i386/kernel/cpu/cpufreq/powernow-k8.c |

The manufacturer could be Uniwill or Arima.

Arima! Thats the one. I am pretty sure Time amd64 Platina's are Arima's W730-K8 DTR model. Sadly there are no bios updates so if the bios is at fault I am still stuffed like a prize turkey.
I think I might have to contact Mr Devriendt and see if he can help if my continued fiddling cannot discover a solution of some description.
Thanks for all the fish!

An interesting update to this problem is that Fedora Core 2 (32bit) seems to have no problems (after a kernel recompile to include the powernow drivers) at all with me changing the cpu speed.
Gonna file it this as a bug report me thinks.
[edit]
Despite spending several minutes changing the cpu speed up and down (getting very bored in the process) on Fedora without any crash I have just had Fedora crash when changing the cpu speed.

| Then it is likely solved in 2.6.7-bk-current as well, as the fedora kernel maintainer is also the cpufreq maintainer... |

From using Fedora which crashes considerably less frequently (why I have no idea) I have discovered changing the speed creates an error. Now this doesn't appear to be a problem at first and you can change the cpu speed several times without any problems despite the error. However eventually this error gets caught in some kind of loop and grabs all the cpu processes and crashes out the laptop.
Error is:-
| Code: | Debug: sleeping function called from invalid context at include/linux/rwsem.h:43 in_atomic():1, irqs_disabled:0

I can only get this info from my Fedora install because it only crashes sometimes on gentoo it crashes all the time and the text kinda cycles up the screen to fast to read. However I suspect the same thing is behind the crash.

Fixed in 2.6.7-bk-current as of today [Linus pulled the cpufreq tree from Dave... ], should be in next fedora kernel... |
