I've got the same problem with a different Laptop but with the same chipset i855 (centrino) lspci output: 0000:00:1f.1 IDE interface: Intel Corp. 82801DBM (ICH4) Ultra ATA Storage Controller (rev 03) Is this problem still present in kernel 2.6.13-rc4? My personal experience is that this bug happens less often now, but I saw it quite recently: Sep 4 19:32:32 [kernel] hda: dma_timer_expiry: dma status == 0x21 Sep 4 19:32:42 [kernel] hda: DMA timeout error Sep 4 19:32:42 [kernel] ide0: reset: success Sep 4 19:57:55 [kernel] hda: dma_timer_expiry: dma status == 0x21 Sep 4 19:58:06 [kernel] hda: DMA timeout error This happened on a Linux version 2.6.13-pcmcia (brodo@sternenlicht) (gcc-Version 3.3.5-20050130 (Gentoo Hardened Linux 3.3.5.20050130-r1, ssp-3 .3.5.20050130-1, pie-8.7.7.1)) #1 Mon Aug 29 11:38:03 CEST 2005 (2.6.13-vanilla with a few PCMCIA bugfixes already in -mm). Still present in 2.6.15-git-as-of-yesterday: [4295276.301000] hda: dma_timer_expiry: dma status == 0x21 [4295286.301000] hda: DMA timeout error [4295286.301000] hda: dma timeout error: status=0xd0 { Busy } [4295286.301000] ide: failed opcode was: unknown [4295286.301000] hda: DMA disabled [4295286.351000] ide0: reset: success Does the problem exist with recent kernels? Thanks. Unfortunately, can't test this any more as my notebook is broken. Should we set this bug to REJECTED - INSUFFICIENT DATA? I guess so... Thanks for update on this anyway. |
