[2.6.24 REGRESSION] BUG: Soft lockup - with VFS
hi all! in the 2.6.24 become i some soft lockups with usb-phone, when i pluged in the mobile, then the vfs-layer crashed. am afternoon can i the .config send, and i bisected the kernel, when i have time. pictures from crash: http://students.zipernowsky.hu/~oliverp/kernel/regression_2624/ -- Thanks, Oliver - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
