Ejecting USB drive causes kernel panic

Postby wannabegeek on Tue Jun 25, 2013 1:37 pm

Hi all...

When I use the eject button to unmount my USB drives, I get an error:
Code: Select all
Writing data to device..etc..


However, there is no write happening...then I pull out the drive anyways and it's fine b/c it was unmounted, as i can no longer see
it with $mount .

Sometimes, ejecting the drive this way causes a kernel panic:
Code: Select all
unable to handle kernel null pointer dereference at 0000000000000000f0


I can perform a cli umount but I often forget and it's annoying...

TIA!

USB drives goes through a serial converter to manage a regular drive(ide or ..) inside a usb case
--that may be the cause of the error

Thanks DrHu...I'm afraid that I didn't subscribe to my own thread...

The bug report does look quit like my problem.

Perhaps a script that kills the process handling the port, in addition to a regular unmount...?

Thanks!
