Subject: Re: Console output corruption
In elks/kernel/printk.c is the following code for parsing a format
string (line 139, right after detecting a '%'):
width = zero = '0';
if (c == '0')
zero++;
while (c >= '0' && c <= '9') {
width *= 10;
width += c - '0';
c = *fmt++;
}
Notice the width is being set to the value of an ASCII '0' character. I
think it should have been set to the integer value 0 (zero) instead.
It looks like, by default, all fields will have a width of whatever the
ASCII code for '0' (48?).

Phil you are the man!
I have just done a quick test and it seems to be fixed:
