FYI: On my Dell OptiPlex GX110 (Intel Pentium III, 933 MHz, 512 MB RAM, i810 chipset), kernel 2.6.18-rc7-mm1 takes drastically longer to boot than 2.6.18 mainline release. Some data points from the respective dmesg outputs: <<<<<<< 2.6.18 <4>[ 26.332472] PID hash table entries: 2048 (order: 11, 8192 bytes) <4>[ 26.334415] Console: colour VGA+ 80x25 >>>>>>> 2.6.18-rc7-mm1 <4>[ 32.102004] PID hash table entries: 2048 (order: 11, 8192 bytes) <4>[ 32.174041] Console: colour VGA+ 80x25 Strange delay in mm wrt mainline.
