-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have notebook with ALi IDE interface: 00:04.0 IDE interface: ALi Corporation M5229 IDE (rev c3) One of scripts called on Mandriva during suspend/resume calls hdparm -U for hdc on suspend and hdparm -R on resume. Now, hdparm -U (HDIO_UNREGISTER_HWIF) completely wipes out hwif reinitializing it. It means, that also hwif->pci_dev is nulled. On hdparm -R (HDIO_SCAN_HWIF) it basically calls hwif_register without initializing pci_dev which means hdc appears in sysfs in different place: before lrwxrwxrwx 1 root root 0 Apr 7 23:53 /sys/block/hdc/device - -> ../../devices/pci0000:00/0000:00:04.0/ide1/1.0/ after lrwxrwxrwx 1 root root 0 Apr 7 23:53 /sys/block/hdc/device - -> ../../devices/ide1/1.0/ this slightly confuses udev that receives a new path and regenerates cdrom links (OK this is no more kernel problem but how I noticed it in the first place :) so what has been cdrom0 before suddenly becomes cdrom1. Looking at ide.c, I do not see any obvious ways to fix it. I appreciate any hint how this can be fixed; alternatively if libpata does not have this issue I am ready to test it.
