Serial console is working Debugger including backtrace is apparently working Now it's based on octeon branch which has greatly improved 64-bit suppor= t. I'm striken by floating bugs of which I don't know the cause yet. What I tried (very incomplete list): - Disabling DMA on I/O controller by writing 0 into hit registers - Checking TLB format. TLB format on loongson is slightly different than on mips FreeBSD works on but it shouldn't have been a problem. After fixing TLB entries nothing changed - Filling cache info completely in appropriate structures When debugging it's almost always is a TLB miss. Either when accessing an address which is supposed to be ok or a wrong pointer. I'm investigati= ng. --=20 Regards Vladimir '=CF=86-coder/phcoder' Serbinenko --------------enig3F402118708BE6723D2877D9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREKAAYFAkwMHvQACgkQNak7dOguQgnd+gEArj2nssElrEJOZ8rA6tJz3+Kf kcKGsXMTyZ+lbNlyCSwA/3zA4B4OeuZf7NGkOdrN8vn5SECjzlHccouI5Z66BL3a =gKat -----END PGP SIGNATURE----- --------------enig3F402118708BE6723D2877D9--
