Description Roland Kletzing 2008-01-04 15:26:18 UTC
Most recent kernel where this bug did not occur: ?
Distribution: OpenSuSE 10.3 with 2.6.24-rc6
Hardware Environment: vmware workstation 6.x on fujitsu siemens lifebook e series
Software Environment: ???

Problem Description:
the module hgafb shows improper behaviour on unload and thus seems to be broken. (should either be fixed or depend on BROKEN then?)

furthermore, the author tells that he doesn`t maintain it anymore, so at least MAINTAINERS file isn`t up to date and could be changed appropriately.
this is the response from the author:
>Dear Roland,
>Thank you for pointing this problem. But I'm not maintaining the  
>driver because I've lost my HGA card in the year 2001.
>Best regards,
>Ferenc Bakonyi

Steps to reproduce:
modprobe hgafb;rmmod hgafb

hgafb: HGA card not detected.
hgafb: probe of hgafb.0 failed with error -22
Device 'hgafb.0' does not have a release() function, it is broken and must be fixed.

Comment 1 Roland Kletzing 2008-01-04 15:43:49 UTC
pardon, i have chosen wrong component, so it was assigned to wrong person
Comment 2 Roland Kletzing 2008-04-12 09:39:50 UTC
still applies for 2.6.25-rc8
Comment 3 Andrew Morton 2008-06-03 17:08:08 UTC
I merged Krzysztof Helt's hgafb-convert-to-new-platform-driver-api-bugzilla-9689.patch which
shodl address this.  Closed.
Comment 4 Roland Kletzing 2008-06-04 14:39:52 UTC
just for tracking, as the patch has been dropped due to two people adressing that at the same time :)
