Per your mail you are using Debian unstable. I am using the same distrib, but my USB memory cards are getting mounted async. What package are you using to do the USB device mounting? usbmount or the HAL+pmount combination (I'm using the latter - pmount uses async by default). If you think the Debian setup is to blame then you should file a bug report. > 2) I understand that sync is slower than async, but IMHO it is a bug, > that it takes more than 20 times longer!? What makes you think a factor of 20 is a bug? What do you base your opinion on? For one thing, the hardware is being treated completely differently and sync mode involves more work overall (this is especially true on FAT based disks, don't know about ext2 although I would imagine the block usage bitmaps would undergo some thrashing that would be avoided in async). People on the linux-kernel and similar mailing lists would be bound to answer this far better though. Maybe the following links can be of interest: http://readlist.com/lists/vger.kernel.org/linux-kernel/22/111771.html http://lkml.org/lkml/2005/5/16/60 Cheers, Eric -- Eric Mountain _______________________________________________ Dirvish mailing list [email protected] http://www.dirvish.org/mailman/listinfo/dirvish
