How much skew is too much?


I am trying to do a linear regression, with a Response Time as my DV with R. When I run a gvlma with the model, the skewness always comes back as assumptions not satisfied. I checked the skewness of the DV and it came out as 0.26. Is this too much skew? I've tried log and sqrt but that really doesn't help.
Can anyone give me some advice with this?

Thank you
