It happens without smartd as well, for example when unpacking few gigabytes of sources for openoffice, after which I find some C source files containing random binary data. (I was overclocking my CPU here though at that time. The logs in this bug report are from not overclocked system though. I will continue to run without overclocking to see if it still corrupts data as well) I googled for the problem and saw more people with such problems, but didn't find any solution. Let me know if you need more info. rychlik:/home/rodo/svn/ooo-build-reference # uname -a Linux rychlik 2.6.25.16-0.1-default #1 SMP 2008-08-21 00:34:25 +0200 x86_64 x86_64 x86_64 GNU/Linux This bug might be also duplicate of #409484 and #359333, but I am not sure whether it is. Also one things which might be related is weird behavior of eth0, which shows lot of dropped packets, rapidly increasing over time: eth0 Link encap:Ethernet HWaddr 00:E0:4D:96:DD:A0 inet addr:192.168.2.36 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:4dff:fe96:dda0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:88101 errors:0 dropped:734521700125 overruns:0 frame:0 TX packets:54394 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:116761891 (111.3 Mb) TX bytes:5470246 (5.2 Mb) Interrupt:251 ~30 secs later: eth0 Link encap:Ethernet HWaddr 00:E0:4D:96:DD:A0 inet addr:192.168.2.36 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:4dff:fe96:dda0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:88196 errors:0 dropped:738364737052 overruns:0 frame:0 TX packets:54502 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:116803324 (111.3 Mb) TX bytes:5479408 (5.2 Mb) Interrupt:251 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
