hwclock ali1535 lockup debug info

Hi all,
Some of this might be dupped, can't tell if my earlier message made it to the list.
I have been experiencing similar problems with rtc accesses causing an apparent system freeze on a Progear tablet. I found another user with a toshiba laptop having the same problem with a commonality of the ALi 1533/1535 Southbridge. This chip also contains the acpi pmu, the M7101 device. I have the datasheet on this chip for reference. I am currently working with linux 2.4.21-rc2 and acpi-20030509 on debian unstable.
I've been trying to pattern the bug's behavior, but I'm pretty much as far as I can go at this time. I started debugging against the rtc module. I traced the "freeze" positions to two places in drivers/char/rtc.c;
set_rtc_irq() + spin_unlock_irq(&rtc_lock);
or
rtc_read() + schedule();
If the system makes it through set_rtc_irq it will stall at rtc_read. These functions strace to the ioctl and read calls from hwclock respectively. The system seems to make it to rtc_read more often than not.
Now the part that brings me back to acpi is a bit of debug output to the console that occurs once the system is "frozen";
evevent-0286: *** Error: No installed handler fo fixed event [00000000]
I was seeing this message repeated approximatly every 10 minutes. Timed it with a stopwatch, something strange about the period, maybe related to how often the TSC resets on this system (400Mhz Crusoe).
The change set that seems to have instigated this bug is BK 1.966.
Hope this helps.
Matt
p.s. I am looking for dsdts from other systems that contain the ALi 1535/1533 chip. My dsdt doesn't contain any of the descriptions for the buttons, lid, ec, battery, etc.

The ALi 1535 contains the following devices,
00:04.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 01)
00:07.0 ISA bridge: ALi Corporation M1533 PCI to ISA Bridge [Aladdin IV]

00:11.0 Bridge: ALi Corporation M7101 PMU
00:14.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
*note the pci id of the ALi 1535 is 1533, not to be confused with the older ALi 1533 chip...
