In which case we should be OK for 2.6.24 and I guess we can hope like heck that the dud patch doesn't leak into mainline. Hopefully Alan will get some time to look into it before 2.6.25 opens. <looks> OK, there's a patch in Jeff's tree "pata_pcmcia: Add support for dumb 8bit IDE emulations" which could be our guy. I've uploaded two patches, against 2.6.24-rc4: http://userweb.kernel.org/~akpm/zl.with.gz origin.patch + git-libata-all.patch http://userweb.kernel.org/~akpm/zl.without.gz origin.patch + git-libata-all.patch - 5ddcddd4dfeb16a9509dad647f509828d6fee605 It would be great if you could test both. If zl.with is bad and zl.without is good then we know that 5ddcddd4dfeb16a9509dad647f509828d6fee605 caused this problem.
