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).
