Hi, Using kernel 3.9.4, with openSUSE 12.1 (KDE 4.7.4 I think), I was running fine for a long time with no problems. Today with openSUSE 12.3 (KDE 4.10.3, Xorg 1.13.2, upgraded on Jun. 10), my machine hung completely. I believe the nouveau driver is at fault rather than KDE or X, so chose this list. Here is a snippet from syslog where some strange stuff begins (while I am not using the computer): 2013-06-14T03:59:34.103035+02:00 linux-zxd7 kernel: [303714.267370] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b0d4 put 0x002003b134 ib_get 0x00000360 ib_put 0x00000361 state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.104254+02:00 linux-zxd7 kernel: [303714.267632] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b134 put 0x002003b194 ib_get 0x00000362 ib_put 0x00000363 state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120218+02:00 linux-zxd7 kernel: [303714.283686] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b194 put 0x002003b1f4 ib_get 0x00000364 ib_put 0x00000365 state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120238+02:00 linux-zxd7 kernel: [303714.283903] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b1f4 put 0x002003b254 ib_get 0x00000366 ib_put 0x00000367 state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120241+02:00 linux-zxd7 kernel: [303714.284025] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b254 put 0x002003b2c0 ib_get 0x00000368 ib_put 0x00000369 state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120244+02:00 linux-zxd7 kernel: [303714.284060] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b2c0 put 0x002003b32c ib_get 0x0000036a ib_put 0x0000036b state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120250+02:00 linux-zxd7 kernel: [303714.284092] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b32c put 0x002003b398 ib_get 0x0000036c ib_put 0x0000036d state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.120252+02:00 linux-zxd7 kernel: [303714.284125] nouveau E[ PFIFO][0000:04:00.0] DMA_PUSHER - ch 2 [Xorg[1761]] get 0x002003b398 put 0x002003b404 ib_get 0x0000036e ib_put 0x0000036f state 0x80000024 (err: INVALID_CMD) push 0x00400040 2013-06-14T03:59:34.124255+02:00 linux-zxd7 kernel: [303714.285213] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF IN 2013-06-14T03:59:34.124266+02:00 linux-zxd7 kernel: [303714.285219] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF 00320051 6ade1280 00000000 04000432 2013-06-14T03:59:34.124267+02:00 linux-zxd7 kernel: [303714.285222] nouveau E[ PGRAPH][0000:04:00.0] TRAP 2013-06-14T03:59:34.124268+02:00 linux-zxd7 kernel: [303714.285225] nouveau E[ PGRAPH][0000:04:00.0] ch 2 [0x0037b10000 Xorg[1761]] subc 0 class 0x5039 mthd 0x0314 data 0x00000108 2013-06-14T03:59:34.124269+02:00 linux-zxd7 kernel: [303714.285236] nouveau E[ PFB][0000:04:00.0] trapped read at 0x006adce9f0 on channel 0x00037b10 [Xorg[1761]] PGRAPH/DISPATCH/M2M_IN reason: PAGE_NOT_PRESENT 2013-06-14T03:59:34.136377+02:00 linux-zxd7 kernel: [303714.299033] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF IN 2013-06-14T03:59:34.136392+02:00 linux-zxd7 kernel: [303714.299041] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF 00320151 6add5080 00000000 04000000 2013-06-14T03:59:34.136394+02:00 linux-zxd7 kernel: [303714.299044] nouveau E[ PGRAPH][0000:04:00.0] TRAP 2013-06-14T03:59:34.136396+02:00 linux-zxd7 kernel: [303714.299047] nouveau E[ PGRAPH][0000:04:00.0] ch 2 [0x0037b10000 Xorg[1761]] subc 0 class 0x5039 mthd 0x023c data 0x00000000 2013-06-14T03:59:34.136404+02:00 linux-zxd7 kernel: [303714.299057] nouveau E[ PFB][0000:04:00.0] trapped read at 0x006add4de0 on channel 0x00037b10 [Xorg[1761]] PGRAPH/DISPATCH/M2M_IN reason: NULL_DMAOBJ 2013-06-14T03:59:34.136406+02:00 linux-zxd7 kernel: [303714.299066] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF IN 2013-06-14T03:59:34.136407+02:00 linux-zxd7 kernel: [303714.299071] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF 00320151 00000380 00000000 04000000 2013-06-14T03:59:34.136417+02:00 linux-zxd7 kernel: [303714.299073] nouveau E[ PGRAPH][0000:04:00.0] TRAP 2013-06-14T03:59:34.136418+02:00 linux-zxd7 kernel: [303714.299075] nouveau E[ PGRAPH][0000:04:00.0] ch 2 [0x0037b10000 Xorg[1761]] subc 0 class 0x5039 mthd 0x0200 data 0x00000001 2013-06-14T03:59:34.136420+02:00 linux-zxd7 kernel: [303714.299476] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF IN 2013-06-14T03:59:34.136420+02:00 linux-zxd7 kernel: [303714.299481] nouveau E[ PGRAPH][0000:04:00.0] TRAP_M2MF 00320151 6abdf380 00000000 04000000 2013-06-14T03:59:34.136421+02:00 linux-zxd7 kernel: [303714.299484] nouveau E[ PGRAPH][0000:04:00.0] TRAP 2013-06-14T03:59:34.136422+02:00 linux-zxd7 kernel: [303714.299486] nouveau E[ PGRAPH][0000:04:00.0] ch 2 [0x0037b10000 Xorg[1761]] subc 0 class 0x5039 mthd 0x0328 data 0x00000000 And here is a stack trace with X crashing a bit later (also while I am not using the computer): 2013-06-14T04:23:09.912406+02:00 linux-zxd7 kernel: [305129.599004] BUG: soft lockup - CPU#0 stuck for 23s!
