Mikhail,
we merged a patch which might be fixing that problem after
2.6.26-git8. Can you give Linus latest a try please ?
Thanks,

This does not help. I try 2.6.26-git17 and the problem still exist.
Please do not trust to kernel timestamp in dmesg. In reality it takes
2-3 times more time before spinlock lockup will be detected.
Here is the summary of kernel parameters I tried:
1) noapictimer -- boot ok, tickless disabled
2) nohpet -- boot ok, (i suppose tickless disabled)
3) clocksource=tsc -- the same as with "nohpet"
4) idle=halt -- need to press buttons to boot
5) none of above -- the kernel freeze after switch to high resolution
mode on CPU0 and detect spinlock lockup 5 minutes
later
