Subject: [PATCH] libata: Use ATA_FLAG_PIO_POLLING for pdc_adma
Date: Wed, 09 Aug 2006 18:36:22 +0800 [thread overview]
Message-ID: <44D9BAA6.2050005@tw.ibm.com> (raw)
pdc_adma was overlooked and broken by the irq-pio patch:
Only HSM_ST_LAST interrupts should be delivered to this LLDD.
Adding ATA_FLAG_PIO_POLLING to pdc_adma fixes the problem (temporarily),
before we convert the irq handler of pdc_adma to handle all interrupts.
Signed-off-by: Albert Lee <albertcc@tw.ibm.com>

Patch against 2.6.18-rc4 and tested ok by Tejun.
