Hi folks, We moved TSM to a new machine and we're getting kernel messages like the ones below. Eventually dsmserv hangs.
The new machine is a 2x2 Core Duo box with 2GB of memory. We've tried both the 2.6.9-34 (and smp) and the current 2.6.9-42.0.3 (and smp) kernels, with IBMtape-3.0.3 for the correct kernel. The machine is running Linux i386, not x86-64, which is our next plan of attack. I found one person who posted something similar off a Japanese IBM site, and painfully translating the text produced results that sound like "huh, that's certainly interesting." Any suggestions? --Jim dsmserv: page allocation failure. order:6, mode:0xd0 [<c0144257>] __alloc_pages+0x28b/0x29d [<c0144281>] __get_free_pages+0x18/0x24 [<f8bc335d>] IBMTapeReadWriteBuffer+0x6b/0x93 [IBMtape] [<f8bc2605>] IBMTapeDriveWrite+0x2d6/0xfc3 [IBMtape] [<f8bb262e>] IBMTapeWrite+0xb5/0xbf [IBMtape] [<c015b0bc>] vfs_write+0xb6/0xe2 [<c015b186>] sys_write+0x3c/0x62 [<c02d47cb>] syscall_call+0x7/0xb [<c02d007b>] packet_rcv+0x17e/0x307 Mem-info: DMA per-cpu: cpu 0 hot: low 2, high 6, batch 1 cpu 0 cold: low 0, high 2, batch 1 cpu 1 hot: low 2, high 6, batch 1 cpu 1 cold: low 0, high 2, batch 1 cpu 2 hot: low 2, high 6, batch 1 cpu 2 cold: low 0, high 2, batch 1 cpu 3 hot: low 2, high 6, batch 1 cpu 3 cold: low 0, high 2, batch 1 Normal per-cpu: cpu 0 hot: low 32, high 96, batch 16 cpu 0 cold: low 0, high 32, batch 16 cpu 1 hot: low 32, high 96, batch 16 cpu 1 cold: low 0, high 32, batch 16 cpu 2 hot: low 32, high 96, batch 16 cpu 2 cold: low 0, high 32, batch 16 cpu 3 hot: low 32, high 96, batch 16 cpu 3 cold: low 0, high 32, batch 16 HighMem per-cpu: cpu 0 hot: low 32, high 96, batch 16 cpu 0 cold: low 0, high 32, batch 16 cpu 1 hot: low 32, high 96, batch 16 cpu 1 cold: low 0, high 32, batch 16 cpu 2 hot: low 32, high 96, batch 16 cpu 2 cold: low 0, high 32, batch 16 cpu 3 hot: low 32, high 96, batch 16 cpu 3 cold: low 0, high 32, batch 16 Free pages: 16168kB (1024kB HighMem) Active:59280 inactive:437127 dirty:32 writeback:1 unstable:0 free:4042 slab:13601 mapped:23499 pagetables:345 DMA free:12560kB min:16kB low:32kB high:48kB active:0kB inactive:0kB present:16384kB pages_scanned:13 all_unreclaimable? yes protections[]: 0 0 0 Normal free:2584kB min:928kB low:1856kB high:2784kB active:82124kB inactive:731244kB present:901120kB pages_scanned:0 all_unreclaimable? no protections[]: 0 0 0 HighMem free:1024kB min:512kB low:1024kB high:1536kB active:154996kB inactive:1017264kB present:1179296kB pages_scanned:0 all_unreclaimable? no protections[]: 0 0 0 DMA: 2*4kB 5*8kB 4*16kB 3*32kB 3*64kB 1*128kB 1*256kB 1*512kB 1*1024kB 1*2048kB 2*4096kB = 12560kB Normal: 188*4kB 87*8kB 71*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 2584kB HighMem: 0*4kB 8*8kB 12*16kB 8*32kB 0*64kB 0*128kB 0*256kB 1*512kB 0*1024kB 0*2048kB 0*4096kB = 1024kB Swap cache: add 52, delete 52, find 0/0, race 0+0 0 bounce buffer pages Free swap: 2096232kB 524200 pages of RAM 294824 pages of HIGHMEM 5540 reserved pages 419227 pages shared 0 pages swap cached
