Public bug reported:
On any version of kernel after 2.6.35-22, get freezes
-- almost always after some tens of seconds
when copying megabytes of data to hard disk using nautilus,
whether source is same HD or flash memory
-- sometimes when allowing an update involving numerous megabytes of
download (I now seldom allow an update when booted into post-2.6.35-22;
cleaning up mess after aborted install not worth the hassle)
-- when launching VirtualBox (again, I avoid trying to run a VM when in
post-2.6.35-22 kernel for
fear of messing up VM file)
-- occasionally when launching Firefox
I've ruled out an X-freeze; once system has frozen because cannot reach
it via SSH over LAN using puTTY
memtest++ run from boot runs for hours without problems
Tried booting with options ,
acpi=off noacpi
fails to boot
Treid booting with options
nomodeset xdriver=radeon
boots okay but same problem occurs
Tried running with cache off (/proc/sys/vm/drop_caches non-zero), makes
no difference
I now run on 2.6.35-22 all the time (running on latest version of kernel
installed: 2.6.35-25-generic
for purposes of this bug report).
