Hi Yani: * Yani Ioannou <yani.ioannou at gmail.com> [2005-09-08 09:56:29 -0400]: > The bus collisions are expected - both the IPMI BMC (not bmcsensors > directly) and the i2c modules you have loaded are competing for the > smbus. However although I've done this (loaded both bmcsensors and i2c > modules and got bus collisions) its never resulted in a lockup. I should also point out: I've been able to get my own ICH5/i801 SMBus locked up so hard that it takes a complete power cycle for the machine to even POST correctly. Ultimately, that's the fault of an extremely unforgiving SMBus client chip somewhere (to say the least) - and there's absolutely nothing the I2C/SMBus driver can do about that. *However* even when this happens for me, *Linux* still runs fine. It's only the SMBus itself that gets locked up. In my case, I can still attempt to read sensors or eeprom or whatever, and of course that fails with tons of collisions - but it doesn't kill the whole kernel. Richard's symptoms seem to implicate the i2c-i801 and i2c-core patches. Regards, -- Mark M. Hoffman mhoffman at lightlink.com
