Hi,
i am currently using linux kernel version 2.6.14 on x86 with Promise
SATAII150 TX2Plus(250G SATA HDD Disk x 2).
But, SATA HDD disk does not become. program execute result of "fdisk
/dev/sda" is "Unable to read /dev/sda".
Work well in linux kernel version 2.6.13.2.
Do not act below since change as result that do debugging.
"[SCSI] use scatter lists for all block pc requests and
simplify hw handlers"

What should I do?
