kernel 2.6.13-rc1-git7 to 2.6.13-rc5 transfer 72MB/s on aha19160 with 15k rpm seagate with reiserfs3 but possible deadlock in heavy IO - rsync ~50000-small files from /mnt/seagate15k/a to /mnt/seagate15k/b ends in middle with deadlock of rsync (3 instances), pdflush, and gam_server all of them in uninteruptible state -- root cannot kill this deadlocked uninterruptibles, so reboot by reset

Please ensure that CONFIG_MAGIC_SYSRQ=y amd that /proc/sysrq is 1 and when
the deadlock happens, do ALT-SYSRQ-T or `echo t > /proc/sysrq-trigger' then
get us the output of `dmesg -s 1000000', thanks.
