After successfully booting the linux kernel ( tried 2.6.18, 2.6.19 or 2.6.20-rc5 ) the machine fails to boot again. It goes thru normal led flashing and fan spinning sequence, like the first time it booted, but stops before actually reading from the boot disk. It refuses to enter OF and the only way to make it boot again is to reset internal PMU via a PMU reset button located inside the chassis. We found experimentally that disabling the SMU (leaving PMU on) in the kernel configuration leads to clean reboot with no problems.... but no /dev/rtc of course and this is a BIG problem! Enabling I2C driver for Dallas RTC or the new RTC Class driver for RTC also locks up the machine on reboot, so I think it's i2c related. We also tried with different models of Xserve (2.0Ghz/DP) with same results.... Any help would be appreciated. Massimiliano (Max) Vegni IT SYSTEMS srl - Rome - Italy
