BTW, with the C1E patches reverted I don't get the WARNING: at /home/rafael/src/linux-next/kernel/smp.c:215 smp_call_function_single+0x3d/0xa2 in the log. Thomas? dmesg with commit 7e3530cd98a0c6ab38f5898e855a5beffab26561 and with the C1E commits (the ones between 8750bf598db6a0ea3475d1cf8da922b325941e12 and aa83f3f2cfc74d66d01b1d2eb1485ea1103a0f4e inclusive) reverted is at: http://www.sisk.pl/kernel/debug/20080616/dmesg-3.log Thanks, Rafael
