http://bugzilla.kernel.org/show_bug.cgi?id=10296 Summary: System freezes after I/O on pata_jmicron device Product: IO/Storage Version: 2.5 KernelVersion: 2.6.24.3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: jniklast@xxxxxx Latest working kernel version: 2.6.23.17 Earliest failing kernel version: 2.6.24.0 Distribution: Gentoo Hardware Environment: JMicron 20360/20363 AHCI Controller (rev 02) on Asus P5W DH Deluxe Mainboard (Intel 975X + ICH7R chipset) Software Environment: gcc 4.1.2, binutils 2.18, glibc 2.6.1-r0 Problem Description: I have pata_jmicron as a module and use a IDE-Harddisk on the JMicron controller. 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. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
