| |
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.
