I have just setup my new amd64 machine and started to copy srces of
HEAD over to it when it suddenly stopped responding (pings still worked).
Didn't use NFS but a tar pipe over ssh for some reason.
I am not yet on serial console so I went to the screen and got s.th.
like the above plus some
ad10: WARNING - WRITE_DMA interrupt was seen but taskqueue stalled LBA=...
from time to time;
the machine is running a 5.2.1 Release (as initial installation).
Is there any way to temporary disable s.th. so I can get a HEAD
srces copied, built and installed ?
would changing hw.ata.ata_dma=0 help ?
And is this problem already fix in HEAD at all ?
Some specs (if it helps):
atapci0: <Promise PDC20378 SATA150 controller> port 0xcc00-0xcc7f,0xdc00-0xdc0f,0xec00-0xec3f mem 0xf3a00000-0xf3a1ffff,0xf3b00000-0xf3b00fff irq 18 at device 8.0 on pci0
atapci1: <VIA 8237 SATA150 controller> port 0xd000-0xd0ff,0xd400-0xd40f,0xd800-0xd803,0xe000-0xe007,0xe400-0xe403,0xe800-0xe807 irq 20 at device 15.0 on pci0
both on board.
ad10: 156334MB <Maxtor 6Y160M0> [317632/16/63] at ata5-master UDMA100
the disk should be attached to the VIA controller.
