ralink2860 crashes in compat_read

[czeidler]

anybody has a clue whats going wrong here? KDL after the first attempt to access the network.

This is hrev43739 but I also saw it before the recent bsd8 driver update.

Clemens,

the driver isn't integrated in FreeBSD, thus not updated periodically. FreeBSD compat layer was updated at least two times for the network layer and one time for the wireless layer.

You could :

• check if anything relevant was fixed in ​http://repo.or.cz/w/ralink_drivers/rt2860_fbsd8.git/tree since initial import in Haiku.
• check what has changed in the compat layer and require a change in the driver.

BTW if the driver is now unstable in trunk, we should probably not integrate it in the image anymore.

[korli]

Have a try to this one too (should be FreeBSD 8 though): ​http://my.ddteam.net/files/rt2860.tar.gz

thx korli, finally got the laptop back and was able to test it. Compiled the driver you posted here but it crashes exactly with the same error in Read. I'm not sure where in the driver "read" is called. Could you give me some hint how the read is forwarded to where it crashes? Or where in the driver the crash happened? thanks!

A complete fresh installation, including repartitioning the hard drive, fixed the problem. However, wifi is not working correctly yet but this is a different problem.
