Hi, I am surprised to see no reaction to such a serious bug (trashing disks is not the best advertising for Linux). I can confirm that the bug is there with both the new and the old pcmcia drivers. If it is a bug of the SCSI driver (aic7xxx) it will affect a large amount of cards due to the diffusion of Adaptec hardware, if it is a bug of mount it should affect all cards... I had another bug for mount (less serious but still disturbing) which was submitted february 26th (29542, it affects both RH7.0 and RH7.1). No reaction on that side too, it is still NEW not even ASSIGNed, is the maintainer of mount in indefinite vacation? When I posted the bug to the RedHat lists RH guys answered in the usual way "put it into bugzilla" however they did not add it was a way to forget it forever... Reported against the wrong component, the kernel handles device locking. Reassigning. This may well be a bug in your device's firmware, though. Is magicdev running ? Hi, sorry for bothering you again.... after the APA1480 stuff. I'll tell you in half a hour (I have to go back home to check) if magicdev is running or not. I would exclude the device firmware since it is the same exact device which worked nicely (=> blocking the ejection) under RH6.0,6.1,6.2 and 7.0 (the last till one week ago until I upgraded to 7.1). Two other identical devices (same model same firmware revision) are regularly blocking the ejection on two 6.2 systems as well. No magicdev is not running. Let me know whether you nedd further infos. |
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.16-3smp i686) With RH7.1 SeaWolf I can eject a MagnetoOptical disk (the drive is a Fujitsu DynaMO640) even though it is mounted and i.e. I cd to it. If I press the eject button the disk comes out with all possible consequences (I trashed already two disks). It did not occur on all previous versions of RH neither in Wolverine as far as I know (I installed it only partially). I do not know whether the problem is in mount or somewhere else, however it seems that mounting does no longer tell the hardware to inhibit the eject. I met the problem on a Latitude C800 with a APA1480A SCSI card and the disk formatted as superfloppy (all drive formatted as one single file system, "mke2fs /dev/sdb") The same hardware combination (and the same disk) worked nicely with RH7.0, a similar machine (Latitude Cpx500) with the same SCSI card and MO drive worked nicely with RH6.1,6.2 and 7.0 Reproducible: Always Steps to Reproduce: 1.format the MO disk ("mke2fs -b 2048/dev/sdb") 2.mount it ("mount -t ext2 /dev/sdb /diskmo") write some data, cd to it (even) 3.press the eject button Actual Results: the disk is ejected (and the system sees it still mounted, of course after a while the system heavily complains) Expected Results: the disk should not be ejected
