2.6.24 still doesn't boot on i486..

Just a follow-up on my earlier bugreport, when
2.6.23 first come out....

2.6.24 seems to not boot on i486-class hardware.
The machine reboots right after "Booting linux"
message. 2.6.22 was the last worked kernel.

The relevant config entries are:

CONFIG_TICK_ONESHOT=y
CONFIG_NO_HZ=y
CONFIG_HIGH_RES_TIMERS=y
CONFIG_GENERIC_CLOCKEVENTS_BUILD=y
CONFIG_X86_PC=y
CONFIG_M486=y
CONFIG_X86_GENERIC=y
CONFIG_X86_CMPXCHG=y <-- is it right?
CONFIG_X86_L1_CACHE_SHIFT=7
CONFIG_X86_XADD=y
CONFIG_X86_PPRO_FENCE=y
CONFIG_X86_F00F_BUG=y
CONFIG_X86_WP_WORKS_OK=y
CONFIG_X86_INVLPG=y
CONFIG_X86_BSWAP=y
CONFIG_X86_POPAD_OK=y
CONFIG_X86_ALIGNMENT_16=y
CONFIG_X86_INTEL_USERCOPY=y
CONFIG_X86_MINIMUM_CPU_FAMILY=4
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_MCE=y
CONFIG_X86_MCE_NONFATAL=y
CONFIG_X86_MCE_P4THERMAL=y
CONFIG_NOHIGHMEM=y
CONFIG_VMSPLIT_3G=y

Compiled with gcc (GCC) 4.2.3 (Debian 4.2.3-2).

This email is also a JFYI-style email. Yesterday
I tried to debug this issue but discovered that the
power unit of that machine failed. Well, it still
works and the machine boots, but at the same time
it smells like frosted/fried plastic ;) So I don't
have i486 hardware anymore to test things on...

And now I wonder if I'm the only person in this world
with i486 machine... ;)

Thanks!
