Before filing a bug, please check whether it has been fixed since
the latest release: run "hg pull -u" and retry what you did to
reproduce the problem. Thanks.

What steps will reproduce the problem?
1. try on NFS mount disk
2. 8g hello_file01.go ; 8l hello_file01.
3. ./8.out hello_file01.go

code:

package main
import ("io"; "os"; "fmt")
func main() {
println(os.Args[1]);
b,_ := io.ReadFile(os.Args[1]);
fmt.Printf("%s", b);
}

What is the expected output? What do you see instead?
It should print out file content, but return null bytes slice.

What is your $GOOS? $GOARCH?
linux
386

Which revision are you using? (hg identify)
