Re: 2.4.14: crashing on heavy swap-load with SmartArray

["Linux Kernel Developer" <linux_developer@hotmail.com>]

    Ok my original response to you may have been wrong.  I think that patch
may not have fixed my problem with the cpqarray driver though I could be
wrong.  If the patch doesn't work for you try downgrading the cpqarray
driver.  Copy the cpqarray.[ch], ida_cmd.h, and ida_ioctl.h files from the
drivers/block directory from an earlier kernel source tree over the ones in
your 2.4.14 kernel source tree.  This fixed the problem I had.
