[Giacomo Catenazzi <cate@cateee.net>]

Hello,

last git changes to git give me the following error (repead very quickly):

sector 14657019, nr/cmr 0/0
bio f7b59280, biotail f7b59280, buffer 0000000, date 0000000, len 36
ide_do_rw_disk-bad command: dev hda: type 2, flags 104c8

[note: manually copied]


I tried bisect:
