Hi,
i am currently using linux kernel version 2.6.15-rc5 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"
- http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=392160335c798bbe94ab3aae6ea0c85d32b81bbc
Test and tried your bug patch, but, result is same.
By result that I do debugging, if queuecommand () of LLD layer returns
result properly, but execute scsi_probe_lun () -> scsi_execute_req ()
-> blk_execute_rq () by thing which is not realized to proc/scsi/scsi
come out . after execute blk_execute_rq(), then cmd->buffer,
cmd->request_buffer is NULL. so, "Model:" in scsi_add_lun() ->
print_inquiry() comes out NULL.
I what whether must do debugging inform can?
what should I do?
