           Summary: ACPI && SMP -> hard lockup within 5 min.
    Kernel Version: 2.5.61
            Status: NEW
          Severity: normal
             Owner: [e-mail]
         Submitter: [e-mail]

Distribution: SuSE 7.0 (modified to run kernel 2.4)
Hardware Environment:dual P3-850 on Asus P2B-DS (Intel BX chipset), 128 Mb
ECC RAM, 30 GB UDMA-33 HD , RTL8029-based Ethernet card 
Software Environment: Kernel 2.5.61, GCC 2.95.3, in-tree ACPI, no modules
Problem Description:

With both ACPI and SMP enabled the machine will lock up hard (no oops, no
keyboard) within about approx. 5 minutes.
Problem occurs with kernels 2.5.60 and 2.5.61, but not with 2.5.59.
Problem does not occur if either ACPI or SMP is turned off.

Steps to reproduce:

Compile kernel with 'Symmetric multi-processing support' and 'ACPI support'
both set to yes. Install, boot, wait.
To (maybe) trigger the bug more likely build a new kernel. My box never
survived a whole build with this configuration.
