https://bugzilla.kernel.org/show_bug.cgi?id=32852 Summary: Random timeouts and unsuccessful resets on JMicron JMB393 PMP Product: IO/Storage Version: 2.5 Kernel Version: 2.6.36.1 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: nemesis@xxxxxxxxxxxx Regression: No Created an attachment (id=53752) --> (https://bugzilla.kernel.org/attachment.cgi?id=53752) lspci About once a month I am greeted with a log entry like the below which completely kicks the JMB393 RAID offline. (This time it is followed by btrfs blowing up, but that's a different problem.) I am going to try kernel 2.6.38.2 now.
