Khashayar, the backtrace in bug #305979 looks quite different to mine. ** Description changed:

It's pretty much always when using firefox, and for instance typing in the URL bar (which causes sqlite activity). My internal drive does not work faster than the USB drive though (probably because it runs 4200rpm and the USB one 5400*), but maybe the bus traffic has more intensive peaks when doing IDE than - when going over USB?

This was solved, but maybe there's a performance regression. + + + Backtrace: + 0: /usr/X11R6/bin/X(xorg_backtrace+0x3b) [0x813164b] + 1: /usr/X11R6/bin/X(mieqEnqueue+0x237) [0x8110ba7] + 2: /usr/X11R6/bin/X(xf86PostMotionEventP+0xc2) [0x80d7d72] + 3: /usr/X11R6/bin/X(xf86PostMotionEvent+0x68) [0x80d7ed8] + 4: /usr/lib/xorg/modules/input//synaptics_drv.so [0xa35fb426] + 5: /usr/lib/xorg/modules/input//synaptics_drv.so [0xa35fdae9] + 6: /usr/X11R6/bin/X [0x80cc467] + 7: /usr/X11R6/bin/X [0x80b089c] + 8: [0xb7f60400] + 9: /usr/lib/xorg/modules/extensions//libdri.so(DRILock+0xfa) [0xb7a3fe1a] + 10: /usr/lib/xorg/modules/extensions//libdri.so(DRIDoWakeupHandler+0x51) [0xb7a3fe81] + 11: /usr/lib/xorg/modules/extensions//libdri.so(DRIWakeupHandler+0x6b) [0xb7a3ef2b] + 12: /usr/X11R6/bin/X(WakeupHandler+0x52) [0x8090662] + 13: /usr/X11R6/bin/X(WaitForSomething+0x1bb) [0x812e87b] + 14: /usr/X11R6/bin/X(Dispatch+0x7e) [0x808c61e] + 15: /usr/X11R6/bin/X(main+0x47d) [0x8071d6d] + 16: /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7b67685] + 17: /usr/X11R6/bin/X [0x8071151] + ERROR: Server Lockup!
