Description sagi yosef 2011-08-17 11:01:42 CEST

Description of problem:

Occasionally (once in a few hours), the desktop becomes garbaged (I use ATI based T60 thinkpad) and only after alt-backspace I recover.

The installation uses the radeon driver and at first it seemed as if something wrong with it.  However, looking at the system logs I got the following, which may indicate of a file-system caching problems in the kernel:

@ sagi yosef

That question (in comment 2) was for you.

Do you still suffer from this bug?

Comment 4 sagi yosef 2012-04-17 05:19:58 CEST

I've uninstalled the system since, so I really don't know, but I'm planning to try again with the new release, so I'll update the status when it's relevant.

Sagi.

Thanks, Sagi

By new release you mean Mageia 2 stable, or do you mean beta 3?

Comment 6 sagi yosef 2012-04-17 22:37:42 CEST

Hopefully Beta 3.

Please give a comment then whatever you find, so even if nothing changed.

Comment 8 sagi yosef 2012-05-01 05:02:42 CEST

Hi.

I've been working with Mageia 2 Beta 3 for a few days now and I'm happy to say that the system is stable and the problem I reported disappeared.

Thanks for your great efforts and hard work!
