Backport patch for i2c-i801 to support Intel 82801EB ICH5
Last modified: 2015-01-04 17:03:39 EST
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705) Description of problem: I can't use lm_sensors on a Dell Optiplex GX270, which uses an Intel 82801EB ICH5 SMBus. The i2c-i801 driver (1.6.5) fails to load on ICH5, so no lm_sensors. Any chance we could get i2c-i801 patched with ICH5 support? The code changes are very straightforward; it acts exactly like ICH4. Basically, you just need to add a #define and use it in two or three places (everywhere that ICH4 is used). The kernel driver i2c-i801 is only version 1.6.5 (rev. 1.2.7). It does not contain support for Intel 82801EB ICH5, which was added in version 2.8.0 (rev. 1.3.3). Version-Release number of selected component (if applicable): lm_sensors-2.8.0-1 How reproducible: Always Steps to Reproduce: modprobe i2c-i801 Actual Results: dmesg reports: i2c-i801.o version 2.6.5 (20020915) i2c-i801.o: Error: Can't detect I801, function 3! i2c-i801.o: I801 not detected, module not inserted. Expected Results: lsmod would show that i2c-i801 loaded properly. Additional info:
This is about the drivers in the kernel, so I assign to the kernel component. greetings, Florian La Roche
LLNL is also hitting what appears to be this same problem. This was reported in IT_53714.
2.6.9 based update is now available for fc2, which should fix this.
