Description Alexander Kaltsas 2008-03-29 08:58:50 UTC 
Latest working kernel version: 2.6.22

Earliest failing kernel version: 2.6.24

Distribution: Arch Linux

Hardware Environment: Pentium III processor @ 900 Mhz, 512 Mbytes RAM, QDI Advance  9 motherboard with VIA chipset.

00:00.0 Host bridge: VIA Technologies, Inc. VT82C693A/694x [Apollo PRO133x] (rev 44)
00:01.0 PCI bridge: VIA Technologies, Inc. VT82C598/694x [Apollo MVP3/Pro133x AGP]
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C596 ISA [Mobile South] (rev 23)
00:07.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 10)
00:07.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 11)
00:07.3 Host bridge: VIA Technologies, Inc. VT82C596 Power Management (rev 30)
 
Software Environment: Arch Linux installation fully updated.

Problem Description: Loading (modprobe) w83781d module doesn't do anything. dmesg doesn't shows anything. Normally (in older kernel version) it would "say" something like w83781d: Found a w83782 chip at ISA... etc. Lm sensors can't work properly. They can't detect the module although it shows up no lsmod.   

Steps to reproduce: Try to modprobe w83781d module at a compatible chipset. Try it on any chipset. It would at least produce a kernel message shown at dmesg saying no compatible device found or something.
Comment 1 Jean Delvare 2008-03-29 09:27:25 UTC 
Please provide the contents of /proc/ioports on the failing kernel, and if possible on the latest working kernel as well for comparison.

I suspect that this is the same problem as:

Comment 2 Alexander Kaltsas 2008-03-29 10:22:49 UTC 
The patch you mentioned works fine. Please include it to the next kernel release. For the record:

Comment 3 Jean Delvare 2008-03-29 11:22:31 UTC 
Created attachment 15506 [details]
Fix resource conflict between w83781d and pnp

I'm attaching the patch for reference. Mark should push it to Linus soon now.
Comment 4 Alexander Kaltsas 2008-03-29 13:22:10 UTC 
Ok, thanks you very much.
Comment 6 Jean Delvare 2008-04-05 00:34:44 UTC 
The fix is not in 2.6.24.y yet, so reopening.
Comment 7 Alexander Kaltsas 2008-04-05 06:33:21 UTC 
I hope that it will be added to the kernel soon.
Comment 8 Jean Delvare 2008-04-05 07:05:09 UTC 
I sent the patch to the stable kernel team already, but I think Greg Kroah-Hartman was on vacation this week, so it will probably take some more days before the patch is accepted and kernel 2.6.24.5 is released.
Comment 9 Jean Delvare 2008-04-19 02:45:50 UTC 
Fixed in 2.6.24.5.
