        Hi again,

        I decided to give my poor P90 a well deserved rest, and I
upgraded to a PP150.
        The beast :
                o Pentium Pro 150
                o 64 MB RAM ECC
                o 450KX/GX chipset
                o Adaptec AIC-7880U SCSI controller
        I've compiled a 2.3.99-pre5 kernel with mostly usual options,
most as modules, but nothing fancy (no SMP, no devfs, ...). Distrib is
Debian 2.2 (meet all the required changes).

        1) If I compile the kernel with support for uniprocessor APIC,
the kernel hang at boot. Simple.

        2) If I compile the kernel without support for uniprocessor
APIC, I boot and run Linux with following problems :

        2a) Error boot messages (also under 2.2.X) :
Apr 25 18:57:40 lagaffe kernel: PCI: Device 00:a0 not found by BIOS
Apr 25 18:57:40 lagaffe kernel: PCI: Device 00:c8 not found by BIOS
        Probably harmless...

        2b) If I leave the box overnight, it crashes :

        In fact, this is almost identical to the crash I reported
earlier on my P90 (March), which is quite a different achitecture (P5
vs P6, IDE vs SCSI).

        2c) When rebooting, it crashes in the fsck and can never
complete a single fsck of the first partition (1GB). At this point,
modules are not loaded and daemons not running, so there is not much
stuff we can blame. 2.2.14 does the fsck without any fuss.

        2d) If I do some kernel compilation, big ftp or other stuff, I
can also crash the box without effort. Oops look the same.

        2e) It seems that the kernel refuse to use the swap
space. "cat /proc/meminfo" always show use of 0B. 2.2.14 use the swap
without any trouble (and swap < 128 MB). Anyway, when the crash occur,
I still have some free memory :
        total: used: free: shared: buffers: cached:
Mem: 64036864 48467968 15568896 0 720896 37167104
Swap: 115146752 0 115146752
MemTotal: 62536 kB
MemFree: 15204 kB
MemShared: 0 kB
Buffers: 704 kB
Cached: 36296 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 62536 kB
LowFree: 15204 kB
SwapTotal: 112448 kB
SwapFree: 112448 kB
        Note that after the crash, the amount of "cached" doesn't want
to go down and seem to only increase. Weird.

        3) 2.2.14 running without any trouble on this box. I need to
go back to 2.2.14 to complete fsck and my kernel compilations. In
fact, I'm running 2.2.14 for months on a similar box.

        I'm willing to provide more information and help investigate
the crash, but remember that I'm not on the mailing list...
        Meanwhile, have fun...


P.S. : I didn't tried Pcmcia yet on this box. That was enoug bad news
for the week...
