Subject: [PATCH] ide-io: increase timeout value to allow for slave wakeup
X-Git-Tag: v2.6.18-rc1~731
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=178184b60979992508130741f16499c360bc9c9a;p=linux-2.6

[PATCH] ide-io: increase timeout value to allow for slave wakeup

During an STR resume cycle, the ide master disk times-out when there is
also a slave present (especially CD).  Increasing the timeout in ide-io
from 10,000 to 100,000 fixes this problem.
