From 4a406856ea6830d8b8dba6a27d9f9331c5f4c13a Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Sun, 19 Jul 2009 14:33:14 +0300 Subject: UBI: print a warning if too many PEBs are corrupted There was a bug report recently where UBI prints: UBI error: ubi_attach_mtd_dev: failed to attach by scanning, error -22 error messages and refuses to attach a PEB. It turned out to be a buggy flash driver which returned garbage to almost every UBI read. This patch makes UBI print a better message in such cases. Namely, if UBI finds 8 or more corrupted PEBs, it prints a warning and lists the corrupted PEBs.
