Hi,
I did HDIO_DRIVE_RESET ioctl, but system hung without any response,
only printed some mesages from kernel(v2.4.20):
hda: DMA disabled
hda: ide_set_handler: handler not null; old=c01ce300, new=c01d4400
bug: kernel timer added twice at c01ce102
would you please help me with it?
Regards
rain.w

Once I understand what the problems all are yes. The BUG() is good, it confirms that what we are both seeing is the same thing - the reset is managing to issue two commands to the controller at the same time. ^ permalink raw reply [flat|nested] 12+ messages in thread

Now we failed the a command. However, I think I need to set a default block hook during the reset process for the drive, channel, hba ... depending on the magnitude of the wrecking ball generated. I need to offline Alan for this core dump. The hang is in the clean ups after the reset. I suspect the driver/hba is in DMA and drive is not.
