None of the above... I did a bisection, it spotted git-scsi-misc.patch.=20 I just run 2.6.24-rc3-mm1 + revert-git-scsi-misc.patch, and it works fi= ne. I guess commit 8655a546c83fc43f0a73416bbd126d02de7ad6c0 "[SCSI] Do not=20 requeue requests if REQ_FAILFAST is set" is the real culprit. The other= =20 commits are touching documentation or drivers I don't use. I'll try=20 to revert only this one this evening. --=20 laurent - To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
