Howdy. I'm not sure whether hardware or stable is the best list for this, but here is my problem. Any info, recommendations, or help will be greatly appreciated. I've got a server running 5-STABLE (updated/built Jan. 22, 2005). It has been running this kernel, a 5.3-RELEASE kernel, and other 5.x branch versions for the last ten or so months now. Previous to this, it was running 4.9-RELEASE. About ten months ago, when I switched from the 4.x branch to the 5.x branch, I immediately began experiencing WRITE_DMA ICRC errors durring disk activity at seemingly random times. At that time I posted to this list and questions the following message: http://groups-beta.google.com/group/mailing.freebsd.questions/browse_thread/thread/17fe5871d823f380/a16568320427152e?rnum=2#a16568320427152e The gist of the message and my current experience is that my hardware (drives, cables, motherboard controllers, etc.) is definately fine and that I've noticed others posting various, possibly-related issues both before and since I posted the above message. I basically ended up working around the problem by running atacontrol in a /usr/local/etc/rc.d/ script that set my drives to PIO4 mode. I then mostly forgot about the problem as everything has since worked fine--that is until just recently. About a week ago (around April 14, 2005) after performing some updates of some ports and configurations, I decided to perform a reboot (quite extranous, I know, but reassuring to verify that all scripts/configs are properly set up the way I want). Just as my system began starting local services, and just after it ran my custom /usr/local/etc/rc.d atacontrol script, I got the following error messages: <Screenshot> Master = PIO4 Slave = UDMA33 Master = PIO4 Slave = BIOSPIO ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=146793208 ad0: FAILURE - READ_DMA timed out GEOM_VINUM: subdisk raid.p0.s0 is down GEOM_VINUM: plex raid.p0 is down Starting mysql. Fatal trap 12: page fault while in kernel mode fault virtual addess = 0xc fault code = supervisor read, page not present instruction pointer = 0x8:0xc04ba88f stack pointer = 0x10:0xd321dc6c frame pointer = 0x10:0xd321dc98 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL0, pres 1, def32 1, gran1 processor eflags = interrupt enabled, resume, IOPL= 0 current process = 4 (g_down) trap number = 12 panic: page fault Uptime: 28s </End Screenshot> This is the first time in ten months I've had issues switching to PIO4 mode during local service startup. I really am not quite sure what happened. Anyhow, I've since rebooted into single-user mode, brought my gvinum-mirror plex back up, and the usual stuff to manually bring my system up. But, I did have one attempt at doing this when I foolishly forgot to manually atacontrol my drives before trying to bring my gvinum plex back up. As it was restoring in the background, I remembered and unthinkingly ran atacontrol and again succeeded in bringing my system down in much the same manner as shown above (only this time with WRITE_DMA errors instead of READ_DMA errors). Anyhow, based on this experience, my two guesses as to the cause of my booting problem is that disk activity from starting the system is causing problems before my disks can be put fully in PIO4 mode (and timing is immaculate) or that the current state of things when atacontrol is executed causes problems. As you can see, I have no idea what the real problem is and wonder if any more info on this/these ata/dma problems is available. I wonder if I'd be better off moving to 4.11 until the root cause of these problems is found. Any help or information anyone?
