ieee1394: dv1394: fix CardBus card ejection (1.75 KB, patch)
2007-01-27 05:05 UTC, Stefan Richter
Details | Diff

Description Miles Lane 2006-09-08 00:46:45 UTC
Most recent kernel where this bug did not occur:  Don't know yet.
Distribution: Ubuntu Development (6.06.1 + devel/devel-extras/security updates)
Hardware Environment: 
X86 Laptop (HP Pavillion dv1240us)
The ieee1394 pcmcia card is a "Western Digital 1394 Cardbus PC Card", model
WDAD003-RNW (The card was made in year 2000)

Problem Description:

I tried testing the patches from
http://groups.google.com/group/linux.kernel/browse_thread/thread/e25d2d810b7cf9cb
applied to 2.6.18-rc5-git1.  Things went pretty well (I attached a firewire
drive and a videocam), until I ran "pccardctl eject" and then popped out the
Firewire card.

Comment 1 Stefan Richter 2006-09-08 01:21:28 UTC
It's obviously a long-standing issue. Cf. 2.6.4's bug 2228.
Comment 2 Stefan Richter 2006-12-01 03:08:24 UTC
Did this happen even though no transmissions were captured from the camera
before? Would it also happen with all FireWire drivers including dv1394 loaded
but no camera connected?
Comment 3 Miles Lane 2006-12-01 18:34:11 UTC
I will test with the latest kernel code and let you know.  It may take a few
days for me to get to this.

Thanks.
Comment 4 Stefan Richter 2006-12-31 08:55:28 UTC
Does also happen with 2.6.19 + IEEE 1394 drivers equivalent to 2.6.20-rc2.

ieee1394: dv1394: fix CardBus card ejection

Comment 6 Stefan Richter 2007-01-27 14:26:12 UTC
Patch committed to linux1394-2.6.git, will send it to Linus after 2.6.20 was
released, i.e. for 2.6.21-rc1. Please reopen this bug entry if dv1394 is still
causing trouble on card ejection.
