Hi Marcelo, Hi Ani,

this bug (marc.theaimsgroup.com/?l=linux-fbdev-devel&m=102977461504322&w=2) is 
still not fixed in latest -BK 2.4.21.

I had the same errors as mentioned in that email. After that patch applied, 
problems are gone and all is working very well.

Patch credits go to Sergey Vlasov.

This fix has been in WOLK for ages.

ciao, Marc
