Hi Alan,

I have a fully reproducible oops on boot with 2.2.21pre2 and 2.2.21pre3.
Kernels 2.2.19, 2.2.21pre1 and 2.4.18rc2 works great.

oops

You want EIP and the call trace. Then look those up in System.map

"une0". Hmm. First guess was it was part of "unexpected interrupt",
but thats the wrong case.

I just did a quick glance at the code, and realised I goofed, and
AMD & Centaur CPUs won't get to the mcheck_init call.
Unrelated to this incident, but a problem all the same.

and finally we have:

I can test any patch in the next hour or tomorrow ;)

Ok, this doesn't make any sense at all.
Your original report says the last thing you saw before the oops was
"CPU serial number disabled."

The code which prints that should run way later than x86_serial_nr_setup
I'll go stare at the code a bit, and see if something jumps out.

You're right x86_serial_nr_setup() is c0278bc8
while c0278bc1 didn't exist in my system.map sorry!

So we died in squash_the_stupid_serial_number()

static void __init squash_the_stupid_serial_number(struct cpuinfo_x86 *c)
{
if (c->x86_capability&(X86_FEATURE_PN) && disable_x86_serial_nr) {
/* Disable processor serial number */
unsigned long lo,hi;
rdmsr(0x119,lo,hi);
lo |= 0x200000;
wrmsr(0x119,lo,hi);
printk(KERN_NOTICE "CPU serial number disabled.\n");
c->x86_capability &= ~X86_FEATURE_PN;
c->cpuid_level = cpuid_eax(0);
}

Quote:}

Given that you see the printk, its one of the last two lines.
I can't see how this can happen.
Although the cpuid_eax function in include/asm-i386/processor.h
needs updating.

2.2 has
extern inline unsigned int cpuid_eax(unsigned int op)
{
unsigned int eax, ebx, ecx, edx;

__asm__("cpuid"
: "=a" (eax), "=b" (ebx), "=c" (ecx), "=d" (edx)
: "a" (op));
return eax;

Quote:}

2.4 has
unsigned int eax;

__asm__("cpuid"
: "=a" (eax)
: "0" (op)
: "bx", "cx", "dx");
return eax;

Though, that shouldn't make any noticable difference unless.

It was!
I've applied that changes and the oops disappear :P
I've attached the 2.2.21pre2+processor.h patch dmesg.

really not bad ;)

You are executing (possibly) text! Looks like an _asm_() procedure is
trashing a register that it shouldn't. Work-around: Don't disable the
serial number until the code is fixed.

Hi.

Just one little question:

Why do ext2 and ext3 not support mount options uid and gid as all the
other filesystems do?

mfg, Erik
