Summary: serial driver causes problems during PM suspend resume

Details:

The serial driver causes problems during PM suspend resume on 2007R1 svn branch

For the issue to recreate enable PM support (Cause Wakeup Event by GPIO PF2)

see PM test - and have PF2 constantly being asserted. (push button)

Suspending console(s)

After a while you will see one or all below reported issues.

If you type chars into the console while running this test - the bugs are more likely to happen.

This issue seems to be already fixed on 2008R1.

1) There are messages like this coming out of the dma driver:

Assertion failed! dma_ch[channel].chan_status != DMA_CHANNEL_FREE && channel < MAX_BLACKFIN_DMA_CHANNEL, arch/blackfin/kernel/bfin_dma_5xx.c, disable_dma, line=417

Unable to attach Blackfin UART TX DMA channel

Assertion failed! dma_ch[channel].chan_status != DMA_CHANNEL_FREE && channel < MAX_BLACKFIN_DMA_CHANNEL, arch/blackfin/kernel/bfin_dma_5xx.c, disable_dma, line=417

Assertion failed! dma_ch[channel].chan_status != DMA_CHANNEL_FREE && channel < MAX_BLACKFIN_DMA_CHANNEL, arch/blackfin/kernel/bfin_dma_5xx.c, get_dma_curr_xcount, line=583
