Hi, i'm having a PPC-405 based board (IBM STB04500 if anyone cares), and i'm using a Maxtor 6Y200L0, a 200GB harddisk drive.
Obviously this uses 48bit addressing, and i'm using linucppc 2.4.21-pre4 devel. The same bug occurs with 2.4.20 release. Users report harddisk corruption, and a quick test showed, that data written to 0x1800000000+x (LBA sector 0xC000000+x/512) is also written to x. (direct O_LARGEFILE-access to /dev/discs0/disc). This will of course corrupt the filesystem. Now my questions: - is this a bug in the IDE low-level interface driver? - or maybe in the kernel? - or maybe fixed in newer versions? - why does the corruption start at this lba sector? User reported that this occurs with different HDD models and brands, too, but only with 48bit-drives. Everything else works perfectly. felix ** Sent via the linuxppc-embedded mail list.
