two to three days
- Heavy disk use (full backup writing, diff against big tarball, bonnie++)
freeze the machine hard, no ping, no sign of live
+ memtest86 shows no problem with the ram
I searched via google and google groups, but found no pertinent idea for my
case: No raid or scsi controller, memory doesn't seem to be an issue as it
works really, really well under 2.2.20 and memtest86 passes too. The system
is generally very stable under 2.2.20 --- but gets killed by 2.4.20.
I run fairly stock kernels (from Debian kernel source packages) with the
win4lin patches, and the ext3 patch in the case of 2.2.20. ACPI is disabled.
Disk access is not tuned in any way, DMA gets enabled by default.
I would be happy to try out suggestions in terms of different kernel
configurations, or patches. I would prefer to stay with the 2.4.* kernel for
now.
Thanks in advance for any pointers. CCs are welcome.

If you don't have a PS/2 mouse plugged into the box add one. If that
doens't help duplicate the crash without win4lin.

My bad: I do have a PS/2 mouse plugged in.

Good idea, will do and will try your most recent rc1-ac? as well.
Thanks, Dirk

Turns out that 2.4.21-rc1 is rock solid. Behaved very well without win4lin,
and is looking good with4lin (survived double bonnie++ tests).
I also unchecked CONIG_ISA, CONFIG_PM, CONFIG_BLK_DEV_PIIX which may have
contributed to the lockups under 2.4.20.
Thanks, Dirk

Enabling or disabling the HIGHME patch is enough to trigger/suppress
hard locking. When HIGHMEM is enabled, locking occurs very easily when
trying to copy a (cloop-mounted) Knoppix image, or even when compiling
a kernel.
I run fairly stock kernels (from Debian kernel source packages) with the
win4lin patch as the only external patch. ACPI is disabled. Disk access is
not tuned in any way, DMA gets enabled by default.

As a follow-up, 2.4.21-rc2 looks fine so far. The only other change was to
enable support the proper mobo i/o chipset, which I should have done earlier.
