Subject: nouveau broken on Riva TNT2 in 5.9.0-rc8: GPU not supported on big-endian
Date: Fri, 9 Oct 2020 23:26:20 +0200 [thread overview]
Message-ID: <202010092326.20482.linux@zary.sk> (raw)
Hello,
I'm testing 5.9.0-rc8 and found that Riva TNT2 stopped working:
[ 0.000000] Linux version 5.9.0-rc8+ (zary@gsql) (gcc (Debian 8.3.0-6) 8.3.0, GNU ld (GNU Binutils for Debian) 2.31.1) #326 SMP Fri Oct 9 22:31:40 CEST 2020
...

[ 14.771782] nouveau: probe of 0000:01:00.0 failed with error -38
big-endian? WTF? The machine is x86.
It works fine with Debian 5.7 kernel (5.7.10-1~bpo10+1):
