Dear all,
We have a DM6446 based custom board, running davinci-linux 2.6.23
kernel,
Now i faced a problem:
The linux kernel can detect IDE HDD attached to the board. It seems
it's works
well on probe HDD and the partitions was detected correctly. But when i try
to mount HDD, it failed. I traced this issue, it seems the kernel can
not read from
the status register on primary channel command block registers.
The ide_wait_stat() routine busy-waits for the drive status to be not
"BUSY", but it
failed. Has anybody know why the status register can be accessed on
booting but can
not be accessed when mount HDD? And how to fix this issue.
Thanks
Frank
