corrupt I/O with USB disk #16
Description
Originally reported by @rvs in a separate Fedora issue: starfive-tech/Fedora_on_StarFive#27 (comment)
And if anyone is curious -- it indeed appears that reading from USB on my board with a stock Fedora kernel produces random results:
[root@fedora-starfive ~]# mount /dev/sda2 /mnt
[root@fedora-starfive ~]# md5sum /mnt/kernel-5.12.0+-1.riscv64.rpm
fdfdba4264bf7a0343b355cf51559b9f /mnt/kernel-5.12.0+-1.riscv64.rpm
AND if I plug it into a different USB socket:
[root@fedora-starfive ~]# mount /dev/sda2 /mnt
[root@fedora-starfive ~]# md5sum /mnt/kernel-5.12.0+-1.riscv64.rpm
cfa4ea2687344fbb2516637490fbb74b /mnt/kernel-5.12.0+-1.riscv64.rpm
And here's some more fun with this:
[root@fedora-starfive ~]# cd /root
[root@fedora-starfive ~]# cp /mnt/kernel-5.12.0+-1.riscv64.rpm 1
[root@fedora-starfive ~]# cp /mnt/kernel-5.12.0+-1.riscv64.rpm 2
[root@fedora-starfive ~]# cmp 1 2
1 2 differ: byte 442264320, line 1690479
Welp, at least it copied quite a bit of bytes before garbage kicked in
