I built a kernel using the same .config file from Ubuntu sources. The system uname -r is 2.6.17.14-ubuntu1-tgspcl. The time to fail lengthened but has generated a similar failure symptom at approximately 25 Hrs TTF.
The failure symptom is BUG: soft lockup detected on CPU#28! dmesg shows: [98810.660884] BUG: soft lockup detected on CPU#28! [98810.805054] Call Trace: [98810.805074] [000000000043411c] smp_percpu_timer_interrupt+0xbc/0x160 [98810.805119] [00000000004109d4] tl0_irq14+0x14/0x20 [98810.805144] [0000000000494170] anon_vma_unlink+0x10/0x80 [98810.805182] [000000000048ec84] free_pgtables+0x44/0xe0 [98810.805211] [000000000048fb3c] unmap_region+0xbc/0x140 [98810.805237] [00000000004907f4] do_munmap+0x174/0x240 [98810.805263] [00000000004908dc] sys_munmap+0x1c/0x40 [98810.805288] [0000000000406c94] linux_sparc_syscall32+0x34/0x40 [98810.805325] [00000000f7dc7388] 0xf7dc7388 Top shows the same problem, the date command is at the top incrementing run time. top - 17:16:08 up 1 day, 4:09, 7 users, load average: 70.12, 70.09, 71.23 Tasks: 402 total, 71 running, 331 sleeping, 0 stopped, 0 zombie Cpu(s): 0.1%us, 3.3%sy, 86.9%ni, 9.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 33257904k total, 23603152k used, 9654752k free, 206488k buffers Swap: 45440440k total, 1419392k used, 44021048k free, 37664k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10991 greg 16 0 3488 1040 888 R 100 0.0 53:30.37 date I have downloaded feisty and will load that on the system next.
