From 967bf623e9f5eecfb056b1ba7e0efd74a21c9c3a Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Tue, 28 Nov 2006 23:11:52 +0000 Subject: [PATCH] Fix Intel/Sharp command set erase suspend bug When we sleep and wait for a suspended operation to be resumed, go back and check until it's ready -- don't just continue after the first time we're woken. This can cause file system corruption.
