           Summary: Strange lockups of timer interrupt (irq 0)
    Kernel Version: 2.6.xx
            Status: NEW
          Severity: normal
             Owner: acpi_config-interrupts at kernel-bugs.osdl.org
         Submitter: mieszcz at zabrze.zigzag.pl


Distribution: gentoo, but tryed with other too.

Problem Description:
When configured kernel with smp and ht, together with acpi then interrupt 0
stops counting after 5min - 1 hour. 
The strange is that when irq0 stops, local interrupt counter are still counting.
If I don't load the ac module of ACPI the problem seems to not occure.
Also system configured without smp seems to be stable.
Steps to reproduce:
run system with smp, load module ac, and wait.
