Subject: 2.6.7 Oops when removing PCMCIA memory card
Date: Thu, 24 Jun 2004 12:52:05 +0300 [thread overview]
Message-ID: <20040624095205.29088.qmail@dag.newtech.fi> (raw)
Hi,
just an into this Oops on my laptop during the following procedure:
- Inserted a PCMCIA adapter with a CompactFlash
- This was recognized and mounted readonly as requested
- A number of pictures was copied from it
- The card was unmounted
- Ejected the PCMCIA adapter and got the Oops
Data:
- Latitude Cpi 300XT Laptop
- Linux 2.6.7 selfcompiled
This seems to be repeatable as it happened again after a reboot.
The Oops report:
==================
