Yes, I provided all information, just BTS somehow not forwarded it.

It is in this message:
http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=346;bug=609389

Also I sent it in private corespondence long time ago,
but is probably lost by now.

I repeate it for clarity


Same machine as in initial report.

Upstream bugzilla page
http://cygwin.com/bugzilla/show_bug.cgi?id=12587

A fix in 2.13-1 was using
patches/i386/cvs-cacheinfo.diff
it should be in upstream sources, but looks
something changed.

For some reason I do not have
/sys/devices/system/cpu/cpu0/cache directory
despite having CONFIG_X86_CPUID=y in kernel.
So, cannot report what kernel says.

Regards,
Witek
