Synopsis: [iwi] iwi firmware load fails after significant uptime

State-Changed-From-To: feedback->closed
State-Changed-By: anholt
State-Changed-When: Sat May 17 18:04:40 UTC 2008
State-Changed-Why: 
I thought this had been closed.  It was fixed with:

commit 47b82a7f674e803139104be78d9fe2e3495be857
Author: jhb <jhb>
Date:   Wed Mar 21 18:40:31 2007 +0000

    Fix an off-by-one error in iwi_init_fw_dma().  It didn't reuse the existing
    DMA memory for a firmware load if it was the exact size needed, thus in the
    common case the driver was constantly free'ing and reallocating the DMA
    buffer and it would eventually begin to fail.  With this fix, iwi0 reuses
    the same buffer the entire time and no longer fails to load the firmware
    after the machine has been up for a while.
