>Description:
Kernel paniced with vinvalbuf: dirty bufs while system under heavy IO on local (ffs) disks.
System has three SCSI disks. First is system disk (80Mb/s), second and third are data disks (160Mb/s). IO activity is issued by unpacking /cdrom/port/ports.tgz archive. One archive unpacked on each disk. Operation repeated in loop. All working ok from few minutes to 3 hours, after that kernel paniced.
Bellow is gdb output.
