Was trying to download 32-12 using mozilla and saw the following: - the download window came up with ?? of ?? downloaded - at this point, mozilla was not responsive, could move windows with the window manager but no updates to the window contents. - top showed no CPU usage for mozilla-bin Tried alt-sysrq-L (was then going to do -D) and got the following messages on the serial console... SysRq : ( IRQ 1-278 |#0): new 2304 us maximum-latency critical section. [stack dump shown] ( IRQ 1-278 |#0): new 374313 us maximum-latency critical section. [stack dump shown] ( IRQ 1-278 |#0): new 374868 us maximum-latency critical section. [stack dump shown] ( IRQ 1-278 |#0): new 374923 us maximum-latency critical section. [stack dump shown] At this point, the system is non responsive. Network operations had stopped, no mouse / display updates, no response to keyboard commands like Alt-SysRq keys. Never saw the output of Alt-SysRq-L on the serial console. The system log did not have anything either, its last message was the one noting that I had logged in for the day. Let me know if you need the serial console output. --Mark H Johnson
