2.4.6 + MediaGX = kernel panic

I have Casio Fiva 102 which is a mini notebook based on Cyrix MediaGX (clone) chipset. 2.4.5 runs like a charm, but 2.4.6, immediately after starting, displays this:

zone(0): 4096 pages.
zone(1): 11648 pages.
zone(2): 0 pages.
Kernel command line: BOOT_IMAGE=linux ro root=304 sb=0x220,5,1,5 Initializing CPU#0
Working around Cyrix MediaGX virtual DMA bugs
Console: colour VGA+ 80x25
kernel BUG at softirq.c:206!

== The rest of the output is passed through ksymoops:

Kernel panic: Aiee, killing interrupt handler!

Tell me if I can provide more information

2.4.7pre3 should fix that one

It works, thanks.
