I just updated my old K6-3 system from CURRENT of Jun 13 to RELENG_5 cvsupped today at 19:53 UTC. When I bring up the network interface, I immediately start getting errors from both the Ethernet card and the second disk (where my /usr partition sits). This is the master on the second IDE bus. The boot disk has not such problems. The errors are: ad2: TIMEOUT - READ_DMA retrying (2 retries left) LBA=10928255 ad2: WARNING - READ_DMA no interrupt but good status xl0: watchdog timeout ad2: TIMEOUT - READ_DMA retrying (2 retries left) LBA=10928319 ad2: WARNING - READ_DMA no interrupt but good status ad2: TIMEOUT - READ_DMA retrying (2 retries left) LBA=10989807 ad2: WARNING - READ_DMA no interrupt but good status ad2: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=11855407 ad2: WARNING - WRITE_DMA no interrupt but good status xl0: watchdog timeout ad2: TIMEOUT - READ_DMA retrying (2 retries left) LBA=10963679 ad2: WARNING - READ_DMA no interrupt but good status I never get failures and the retry count never goes below 2, but the system is a bit slow. If I don't bring up the network, it runs fine with no errors at all from the disk.
