Most recent kernel where this bug did not occur: Distribution: ALL Linux kernel Hardware Environment: ULI M-1573 south Bridge chip Software Environment: Standard Linux Kenrel Problem Description: The alim15x3.c havn't been update for 3 years. Recently when we use this "ULI M1573" south bridge chip found that can't mount CDROM(VCD) smoothly, must waiting for a long time. After I check the "ULI M1573" south bridge datasheet, I found the reason. The reason is the "ULI M1573" version in the Linux is "0xC7" not "0xC4" anymore So I was modified the source than it was successed. Steps to reproduce: Origianl kerenl source as below: ================================ if(m5229_revision <= 0x20) tmpbyte = (tmpbyte & (~0x02)) | 0x01; else tmpbyte |= 0x01; Below is modify source: ================================= if(m5229_revision <= 0x20) tmpbyte = (tmpbyte & (~0x02)) | 0x01; else if(m5229_revision == 0xC7) tmpbyte |= 0x03; else tmpbyte |= 0x01;
