Subject: Re: [PATCH] 2.5.13 IDE PIO mode Fix
Date: Sat, 4 May 2002 12:15:18 +0200 (MEST) [thread overview]
Message-ID: <UTC200205041015.g44AFIV16086.aeb@smtp.cwi.nl> (raw)
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.
