I can't reproduce this on clean 2.6.18-rc1.

I have tried #define SCAN_BLOCK_SIZE 2048 and #define SCAN_BLOCK_SIZE 1024 Unfortunately it doesn't change anything.

Please try something like this on tty1 isic -s rand -d your ip (http://www.packetfactory.net/Projects/ISIC/) on tty2 kml_collector (http://www.stardust.webpages.pl/files/o_bugs/kml/ml/kml_collector.sh)
(I have tried to read random files from /sys on vanilla kernel, but I can't reproduce that lockup)
