This is a multi-part message in MIME format. --Multipart_Thu__16_Oct_2003_23_17_47_+0900_0865e200 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Hi. The original ata_reset() lost ATA-master drive and remove main file system after suspend/resume. Of cource it occors panic! I think that the ata_reset() in ata-lowlevel.c is bogus and I can not understand the code. So I study ATA and rewrite ata_reset() completely. New device detect algorism using ata command ATA_IDENTIFY_DEVICE and ATA_IDENTIFY_PACKET_DEVICE for judge ATA and ATAPI devices. This patch works fine with my TOSHIBA Libretto L5. But not yet test ATAPI devices and ATA-slave channel. Maybe there is need to adjust wait DELAY time. Please test and replace ata_reset(). I hope this solve ATAng troubles. -- Hiroyuki Aizu --Multipart_Thu__16_Oct_2003_23_17_47_+0900_0865e200 Content-Type: application/octet-stream; name="ata-lowlevel.c.diff" Content-Disposition:
