Bubba hangs

Post by Gunnarsson »

Hi

I've just got my bubbaTWO 1TB but when I try to transfer my music it just hangs after 5min or so. Then I cant acess it in any whay but it responds to ping.
So then I have to pull the plug on it and restart. I have the latest F/W.

Dont know what to do... :cry:

The last lines in Syslog before the hang:

DMA error

Post by booskunk »

I started to get this same DMA error today. I wonder if this is a symptom of overheating.

Try and check out HHDtemp then. This shouldn't be a problem though unless Bubba is in a confined space. My Bubba runs at just under 40 degrees, which is a safe temperature.

Do I need to compile hhdtemp from the source? I tried installing smartmontools right after getting my Bubba Two but couldn't get it to work.

Regarding my hang, local disk accesses don't seem to be a problem. But copying files to the Bubba samba server over the network causes the hang. I checked the case temperature with a laser thermometer and it was 38 degrees celcius.

Gunnarsson and others;

Did you upgrade to the latest kernel (2.6.26.5-8), according to http://forum.excito.net/viewtopic.php?t=1685&start=30? This should solve this issue.

If the upgrade didn't work, please email support@excito.com and we'll figure out why. The new kernel fixes exactly your problem.

Installed hddtemp. /dev/sda temperature reaches 43. I did an rsync transfer but didn't see the problem. The hang happened when I did a samba transfer. I also had an ssh shell going.

OK, 2.6.26.5-8 makes things better, but there is still a problem.
Summary of tests so far:

2.6.26.5-2 Vista samba copy to external esata: DMA error hang
2.6.26.5-2 Vista samba copy to internal drive: DMA error hang
2.6.26.5-2 Vista rsync copy to internal drive: success
2.6.26.5-8 Vista samba copy to external esata: hang
2.6.26.5-8 Vista samba copy to internal drive: success
2.6.26.5-8 XP samba copy to external esata: success

The DMA errors are gone, but I still get a hang when using a Vista client and samba to the external drive. I noticed that the "Bubba freeze copy files half solved ;)" thread also reported problems with Vista as the client. The 2.6.26.5-8 hang is not as hard as the 2.6.26.5-2 hang. Networking is still alive, because my ssh session will echo characters (after a long delay) but won't give a new prompt.

Found a Samba nmbd crash, but it doesn't explain the ssh and web hang:
