Subject: [PATCH] 2.5.14 IDE CD-ROM PIO mode
Date: Tue, 07 May 2002 17:51:18 +0900 [thread overview]
Message-ID: <3CD79586.63E17164@cinet.co.jp> (raw)
I could not use CD-ROM drive [PIO mode] on 2.5.14.
Error messeges are follows.
May 7 11:05:03 sarah kernel: hdc: cdrom_read_intr: data underrun (4294967292 blocks)
May 7 11:05:03 sarah kernel: end_request: I/O error, dev 16:00, sector 92
May 7 11:05:03 sarah kernel: Buffer I/O error on device ide1(22,0), logical block 22
This patch works fine for me. Please check it.
