This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Same issue here dmesg ..... it87: Found IT8720F chip at 0x290, revision 2 it87: in3 is VCC (+5V) it87: in7 is VCCH (+5V Stand-By) ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region ECRE [0x290-0x2af] ACPI: Device needs an ACPI driver ..... modprobe it87 WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Error inserting it87 (/lib/modules/2.6.29.4-167.fc11.x86_64/kernel/drivers/hwmon/it87.ko): Device or resource busy uname -a Linux mn4 2.6.29.4-167.fc11.x86_64 #1 SMP Wed May 27 17:27:08 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux This is apparently an intentional error - it prevents it87 from using the same I2C bus as the acpi code. Two sets of code accessing the same bus is dangerous, I guess what is really needed is a common access point and a arbitrator. Having said that both machines I use this on have been fine with the clash for 4-5 years and no obvious problems before this check was added, and now I've disabled it they've been fine again for the last 6 weeks or so. You can disable this check by passing acpi_enforce_resources=lax on the kernel command line in grub, which solves the issue for me. (But be aware of potential undesired but unspecified consequences.) I would much prefer kernel stability over some marginally useful functionality. Another 'me too'. I happened to notice this when 'fancontrol' stopped working after upgrading from F11 to F12 (i686). FWIW, I've got an ASUS M2N-SLI DELUXE mobo. Still same problem in F13 alpha. same problem here my mobo is DFI nForce4 ultra-d, diagnostic chip it8712F [root@amd64 ~]# modprobe -v it87 insmod /lib/modules/2.6.33.4-95.fc13.x86_64/kernel/drivers/hwmon/it87.ko FATAL: Error inserting it87 (/lib/modules/2.6.33.4-95.fc13.x86_64/kernel/drivers/hwmon/it87.ko): Device or resource busy [root@amd64 ~]# lsmod | grep i2c i2c_nforce2 6566 0 i2c_algo_bit 4781 1 radeon i2c_core 24507 5 i2c_nforce2,radeon,drm_kms_helper,drm,i2c_algo_bit --- from boot.log Starting lm_sensors: loading module it87 [60G[[0;32m OK [0;39m] ...
