2001-04-11 Thread Petr Vandrovec
Hi, Alan, Linus, please apply this patch to matroxfb. It fixes complaints from people that screen is black after they exit from X back to console. Matrox driver does not know that it should return hardware state back to initial state after switch, but matroxfb relies on that (XF3 did that...).

Coudl the problem be in the NIC driver not in the alloc_skb? I have used both 2.4.{1,3} for some time and never seen this corruption. I use ping -f with various packet sizes for stress testing my IPSec boxes... these do quite a bit of extra skb creation as an IPSec header sometimes does not
