The old error history was cleared in ata_ering_clear(). It only sets ATA_EFLAG_OLD_ER eflags, but the err_mask was not cleared. So ata_ering_map() still iterates the old error history.
This causes problem, for example, wrong probe trials count were returned in ata_eh_schedule_probe(), which in turn causes SATA link speed to be slowed down to 1.5Gbps.

Hi Jeff,
This patch fixes an old regression introduced in 2.6.37-rc1 of commit d902747.
So it should be included into stable releases since 2.6.37.
You should have included: Cc: stable@xxxxxxxxxxxxxxx # 2.6.37+ after your signoff in this case.
