 Posted: Tue May 13, 2003 1:34 pm Post subject: gentoo-sources-2.4.20 and lm_sensors |
 |
|
Somewhere along the way my lm-sensors stopped being able to set the thresholds. If I issue a "sensors -s", I get :
via686a-isa-6000: Can't access /proc file for writing;
Run as root?
This as root! The i2c-proc module (and all the others that used to work) are loaded. A normal "sensors" and "sensors-detect" work as expected.
i2c-dev is also not loaded, and "modprobe -kv i2c-dev" just returns with nothing loaded and no errors printed.
This started with some (I dont know which) kernel upgrade.

billk: did you solve your problem? I'm having the same problem:
| Code: | [ root ]:~ > sensors -s
as99127f-i2c-0-2d: Can't access /proc file for writing;
Run as root? |
Yes I'm running as root.
lsmod:
| Code: | Module Size Used by Not tainted
i2c-dev 4100 0 (unused)
i2c-viapro 3920 0 (unused)
w83781d 20464 0
i2c-proc 6704 0 [w83781d]
i2c-core 13832 0 [i2c-dev i2c-viapro w83781d i2c-proc]
sd_mod 10252 0 (autoclean) (unused)
scsi_mod 52212 1 (autoclean) [sd_mod]
floppy 45788 0 (autoclean)
rtc 6972 0 (autoclean)
visor 8776 0 (unused)
usbserial 16572 0 [visor]
usb-uhci 21068 0 (unused)
usbcore 54624 1 [visor usbserial usb-uhci] |
What is wrong, it has until now been working fine.

No - still have the problem. When did yours stop working: can you tie it to a new kernel or some such?
I think mine worked prior to 2.4.20-r2. |

Same here, it worked fine in 2.4.19-r(something) but not in 2.4.20-r2, and not in -r5

Yeah, same problem here, no solution yet. Maybe it deserve a bug report...

try the sys-apps/i2c.
i had the some problems with outdated i2c modules in gentoo2.4.20 and lm-sensors needs 2.7.0 versioned i2c modules, so compile the i2c things as modules und emerge i2c, it will upgrade your modules.
for me it works fine. |

Others have the same problem. I have i2c-2.7.0 and lm-sensors-2.7.0-r1.
Wrote a bug at lm_sensors. Worked with the developers on it for awhile.
They were having me try patches and various things. Nothing seems to work.
Seems like they gave up, haven't heard from them in awhile.
I have the same chipset, it seems like it is mainly an issue with it.
One thought was the isa address of 6000 for the via686a-isa-6000.
If you want 'sensor -s' to work, I believe during my testing that if you use Smbus instead it worked. Just not 'ISA' |

for me via-686a is working perfectly with ISA.
i'm using ksensors for watching the sensors output  .
MoBo is MSI K7T Turbo (not very new but works perfectly).
try some bios updates, compile your kernel with everything you need for i2c like proc iface und devices (compile as module). then emerge i2c and watch sensors-detect what modules are working, than it should run without problems. |

Lm_Sensors works fine on mine too in ISA, I was refering to using the command
Your saying that works on yours?
I use gkrellm2 to monitor mine.
Plus I worked with the developers on it and I have everything. They
don't know why some people can do it either. |

Tried all that in the past ... doesnt work. Seems many (but not all) those having problems are using gentoo, maybe something distro specific?
This works without fail though (so sensors -s is redundant anyway)
echo "1.7 1.8" > /proc/sys/dev/sensors/via686a-isa-6000/in0
echo "40 35" > /proc/sys/dev/sensors/via686a-isa-6000/temp1
echo "56 51" > /proc/sys/dev/sensors/via686a-isa-6000/temp2
echo "3400" > /proc/sys/dev/sensors/via686a-isa-6000/fan1 |
