I have been getting a number of kernel oopsen that can be related to lm_sensors or RSBAC (for the lm_sensors folks: http://rsbac.org/). They seem to occur when there is a lot of disk IO going on, either in the file system (in the first oops below I was copying a large file from a ext3 over Jari Ruusu's AES loop to a regular ext3), or swapping (my swap is also on AES loop). The kernel is 2.4.22. In addition to RSBAC and AES loop, it has PaX in it. In all, or at least most of the cases, rsbac has been in global softmode. It could also be that the first oops below is entirely separate case from the others - it (based on the look of the stack) has occured only once, while the latter sort has occured some 20 times. If it doesn't seem likely this has anything to do with your project, feel free to ignore this mail. Some info of the system: - Kernel vanilla 2.4.22 - RSBAC 1.2.2 - lm_sensors 2.6.5 - sensors-detect (pressed enter to every prompt): System vendor: ABIT We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver 2c-i801' for device 00:1f.3: Intel 82801BA ICH2 Use driver 2c-riva' for device 01:00.0: GeForce2 MX Probe succesfully concluded. We will now try to load each adapter module in turn. Load 2c-i801' (say NO if built into your kernel)? (YES/no): Module loaded succesfully. Load 2c-riva' (say NO if built into your kernel)? (YES/no): Sep 28 11:39:03 woods kernel: i2c-i801.o version 2.6.5 (20020915) modprobe: Can't locate module i2c-riva Loading failed ()... skipping. ** Note: i2c-riva module is available at ** http://drama.obuda.kando.hu/~fero/cgi-bin/rivatv.shtml Do you now want to be prompted for non-detectable adapters? (yes/NO): To continue, we need module 2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/no): Module loaded succesfully. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. That often includes address 0x69 (clock chip). Next adapter: bt848 #0 (Bit-shift algorithm) Do you want to scan it? (YES/no/selectively): Sep 28 11:39:20 woods kernel: i2c-dev.o: i2c /dev entries driver module Client found at address 0x30 Client found at address 0x50 Probing for erial EEPROM (SDRAM DIMM)'... Success! (confidence 1, driver eprom') Probing for DC monitor'... Failed! Client at address 0x60 can not be probed - unload all client drivers first! Next adapter: SMBus I801 adapter at 5000 (Non-I2C SMBus adapter) Do you want to scan it? (YES/no/selectively): Can't open /dev/i2c[-/]2 Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. Do you want to scan the ISA bus? (YES/no): Probing for ational Semiconductor LM78' Trying address 0x0290...

Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver eprom' (should be inserted): Detects correctly: * Bus t848 #0' (Bit-shift algorithm) Busdriver NKNOWN', I2C address 0x50 Chip erial EEPROM (SDRAM DIMM)' (confidence: 1) Driver 83781d' (should be inserted): Detects correctly: * ISA bus address 0x0290 (Busdriver 2c-isa') Chip inbond W83627HF' (confidence: 8) I will now generate the commands needed to load the I2C modules. Sometimes, a chip is available both through the ISA bus and an I2C bus. ISA bus access is faster, but you need to load an additional driver module for it. If you have the choice, do you want to use the ISA bus or the I2C/SMBus (ISA/smbus)? Use of uninitialized value in string eq at /usr/sbin/sensors-detect line 2697. Use of uninitialized value in string eq at /usr/sbin/sensors-detect line 2709. WARNING! If you have some things built into your kernel, the below list will contain too many modules. Skip the appropriate ones!
