| Post subject: | DMA problem with hard disk - system hangs |
Hi, Has anybody seen this error when system just hangs and hard disk light is continuously on? The following messages appear in /var/log/messages file. *************************** Aug 29 12:10:28 tv_dxr kernel: hdb: dma_timer_expiry: dma status == 0x40 Aug 29 12:10:28 tv_dxr kernel: hdb: (__ide_dma_test_irq) called while not waiting Aug 29 12:10:28 tv_dxr kernel: hdb: status timeout: status=0xd0 { Busy } *************************** The machine is giga-byte GA-7DXR and the same machine runs Fedora Core 2 without any such problem. KnoppMyth is R4.1(the latest one). Currently I am running the hard disks with DMA disabled but this does not give me optimal performance. Any suggestions? I have tried googling but all I could see was that many many people have this problem with kernel 2.4.25 but could not find solution. thanks in advance. PK |

That's a Via chipset. Search for "DMA" and "Via". Be sure to check the box to require all terms. Bottom line is that there is a known DMA bug in the chipset. Fedora core is using a newer kernel than the current version of KnoppMyth. The next version will have an updated kernel by all reports. |

Thanks tjc for the reply. By new version having updated kernel, did you mean new version of KnoppyMyth? I am now more eager to see new KnoppMyth as I like this distro very much. Thanks again. PK |

Yes, for the next version (R5) of Knoppmyth I believe Cesman has mentioned a 2.6 kernel. |
