| |
I found this bug in 2.5.10 first. And caused ext2 FS corruption. We are porting Linux to PC-9801 architecture (made by NEC Japan). It has PIO ONLY IDE I/F. So please check PIO mode too. # Our porting status - 2.2.x/2.4.x done and updating. 2.5.x partial.

Excellent! It was introduced in 2.5.9 and still exists in 2.5.13, and caused superblock corruption for me. This fixes it.
