Regression in marvell-nand

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Boris and all,

I'm seeing a severe regression with the NAND driver on a PXA3xx platform
caused by b25251414f6e00 ("mtd: rawnand: marvell: Stop implementing
->select_chip()"). Since that commit, I'm seeing lots of messages like
this during boot:

[    5.480730] Bad eraseblock 702 at 0x0000057c0000
[    5.485936] Bad eraseblock 703 at 0x0000057e0000

[    5.496544] Bad eraseblock 705 at 0x000005820000

Eventually followed by the UBI layer acting up:

The commit before is working just fine. I haven't dug any further than
bisecting yet however.

Any idea?


Thanks,
Daniel
