I can't trigger them just by running glxinfo like Kevin, however opening a few tabs containing large images in firefox does t= he trick and also freezes my system for about a minute. cat /debug/x86/pat_memtype_list before the bug gives me ~17000 lines, of th= e form write-combining @ 0xeff70000-0xeff71000 write-combining @ 0xeff71000-0xeff72000 write-combining @ 0xeff72000-0xeff73000 write-combining @ 0xeff73000-0xeff74000 write-combining @ 0xeff74000-0xeff75000 write-combining @ 0xeff75000-0xeff76000 write-combining @ 0xeff76000-0xeff77000 write-combining @ 0xeff77000-0xeff78000 write-combining @ 0xeff78000-0xeff79000 write-combining @ 0xeff79000-0xeff7a000 checking pat_memtype_list after triggering the bug produced ~25000 lines, so I'm thinking a diff isn't really helpful. you can find my kernel log @ http://dev.gentoo.org/~dirtyepic/misc/logs/20090508-kern.log what other info do you need? --=20 gcc-porting, by design, by neglect treecleaner, for a fact or just for effect wxwidgets @ gentoo EFFD 380E 047A 4B51 D2BD C64F 8AA8 8346 F9A4 0662 --Sig_/ysoNmJ5A9hYqFS6=iJW0PeP Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) iEYEARECAAYFAkndZMIACgkQiqiDRvmkBmL9YACeNElxaKhnFStSAlVk49bxfDP+ zbcAoJ84dkvZdH9ZMuAeCUIcenQKQ8MV =S1o5 -----END PGP SIGNATURE----- --Sig_/ysoNmJ5A9hYqFS6=iJW0PeP-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
