From 914616a3c2a54504f3b0eda0b67fcd32226b3e83 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 25 Jun 2007 21:47:11 +0900 Subject: [PATCH] libata: fix infinite EH waiting bug When EH gives up after repeated exceptions, it doesn't't clear the PENDING bit on exit which leaves PENDING bit set without EH actually scheduled. This makes ata_port_wait_eh() to wait forever makes rmmod hang on such port. Fix it by clearing the flag.
