I've seen this kind of lockup (according to sysrq-T) on different boxes: 1) ope RAID: mylex 352 drivers: e100, dac960 .config: http://sysadminday.org.ru/2.6.1-io_lockup/ope/.config 2) terror RAID: megaraid 320-2 drivers: e1000, megaraid2 .config: http://sysadminday.org.ru/2.6.X-lockup/terror/.config 3) mirror drivers: e100, aic7xxx, md, netconsole .config: http://sysadminday.org.ru/2.6.X-lockup/mirror/.config I also saw the same symptoms on a fourth box, but I'm not shure about this one because it didn't use to be attached to serial console at that time. For this box: RAID: Compaq smart 2 drivers: tlan,epic100,cpqarray -- Best regards, Sergey S. Kostyliov Public PGP key: http://sysadminday.org.ru/rathamahata.asc
