No, this box doesn't have any serial ports.

Without any patches on top it boots, but the fan is turned 100% on as soon as the ACPI modules get loaded, regardless of the temperature (normally it does that above 75^o C, which is impossible to get normally, because there are 3 temperature trip points below that level; generally the hardware only does that when overheating). After that, things start to go _very_ slow, like 10x slower than usually in X and somewhat slower in the fb console, but I was able to get a dmesg output. This is reproducible 100% of the time. With commit 7e3530cd98a0c6ab38f5898e855a5beffab26561 reverted the box seems to work normally. However, while I was writing this message, ACPI decided it was overheating and emergency shut down the box, although that was completely wrong. Next time I'll try with the C1E patches reverted. The .config is at: http://www.sisk.pl/kernel/debug/20080616/next-config dmesg output without any patches is at http://www.sisk.pl/kernel/debug/20080616/dmesg-1.log dmesg output with commit 7e3530cd98a0c6ab38f5898e855a5beffab26561 reverted is at: http://www.sisk.pl/kernel/debug/20080616/dmesg-2.log (they look pretty similar to my untrained eye, but well). Thanks, Rafael
