Whenever I do some I/O on that harddisk the I/O waiting load goes up within a few seconds until it is at or close to 100% which renders the system unusable. Magic SysRq makes a graceful reboot possible sometimes. Steps to reproduce: 1. Do some I/O on a IDE-Harddisk which uses pata_jmicron -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
