I get repeated crashes with -STABLE on my VAIO Z600NE. Using a 4.3-RELEASE
(even with the latest -STABLE world), I have no problem. No PCCARD was
inserted.
Generally, the kernel crashes shortly after starting XEmacs+Gnus under
KDE.
Sources (kernel + world) are from about 4 hours ago.

Does it look like a known problem?
