A quote from an e-mail from Damien (https://www.spinics.net/lists/stable/msg185436.html): --------------------------------------------------------------------------- Re: [PATCH] Revert "scsi-mq: Always unprepare before requeuing a request" >> For an unknown reason this patch causes the boot process to hang on >> PowerPC systems: > > OK, dropped it from fixes for now. It means that commit 70e42fd02c46e2aa9ab07b766d418637e3a51de7 "scsi: sd_zbc: Write unlock zone from sd_uninit_cmnd()" will need to be reverted too as it will not solve the potential deadlock anymore. Bart's patch was needed for it to work. --------------------------------------------------------------------------- Bart.
