Subject: [SCSI] mptfc: abort of board reset leaves port dead requiring reboot
X-Git-Tag: v2.6.18-rc1~1092^2~10
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d6be06c84da9626b10443c664ee55bda96fb3514;p=linux-2.6

[SCSI] mptfc: abort of board reset leaves port dead requiring reboot

The driver uses msleep_interruptible() in the code path responsible
for resetting the card's ports via the lsiutil command.  If a
<ctrl-c> is received during the reset it can leave a port in such
a state that the only way to regain its use is to reboot the system.
Changing from msleep_interruptible() to msleep() corrects the problem.
