It is 100% reproducible, by opening a 350MB tar file into ubifs volume on NAND flash, and starting erase of NOR flash partition right after that. If I don't start NOR erase, everything works fine. Also, If I run sync after tar, no problem occurs. The NOR flash is 32MB Spansion, NAND is 4GB Samsung. The error messages are as follows: UBI error: ubi_io_write: error -5 while writing 2048 bytes to PEB 5812:12288, written 0 bytes UBI warning: ubi_eba_write_leb: failed to write data to PEB 5812 UBI: recover PEB 5812, move data to PEB 19400 UBI error: ubi_io_read: error -74 while reading 512 bytes from PEB 5812:512, read 512 bytes UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 19400:512, written 0 bytes UBI warning: recover_peb: failed to write to PEB 19400 UBI: try again UBI: recover PEB 5812, move data to PEB 19401 UBI: run torture test for PEB 19400 UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 19401:512, written 0 bytes UBI warning: recover_peb: failed to write to PEB 19401 UBI: try again UBI: recover PEB 5812, move data to PEB 19402 UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 19402:512, written 0 bytes UBI warning: recover_peb: failed to write to PEB 19402 UBI: try again UBI: recover PEB 5812, move data to PEB 19403 UBI error: ubi_io_write: error -5 while writing 512 bytes to PEB 19403:512, written 0 bytes UBI warning: recover_peb: failed to write to PEB 19403 UBI warning: ubi_ro_mode: switch to read-only mode UBIFS error (pid 1149): ubifs_wbuf_write_nolock: cannot write 2522 bytes to LEB 389:10240, error -5 UBIFS warning (pid 1149): ubifs_ro_mode: switched to read-only mode, error -5 UBIFS error (pid 1149): do_writepage: cannot write page 0 of inode 30708, error -5 UBIFS error (pid 1149): make_reservation: cannot reserve 858 bytes in jhead 2, error -30 UBIFS error (pid 1149): do_writepage: cannot write page 2 of inode 29486, error -30 UBIFS error (pid 1149): make_reservation: cannot reserve 721 bytes in jhead 2, error -30 UBIFS error (pid 1149): do_writepage: cannot write page 1 of inode 30070, error -30 UBI error: ubi_io_write: error -5 while writing 2048 bytes to PEB 5022:88064, written 0 bytes UBI warning: ubi_eba_write_leb: failed to write data to PEB 5022 UBI: recover PEB 5022, move data to PEB 19404 UBI error: ubi_io_read: error -74 while reading 512 bytes from PEB 5022:512, read 512 bytes UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19404 UBI: try again UBI: recover PEB 5022, move data to PEB 19405 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19405 UBI: try again UBI: recover PEB 5022, move data to PEB 19406 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19406 UBI: try again UBI: recover PEB 5022, move data to PEB 19407 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19407 UBIFS error (pid 1044): ubifs_wbuf_sync_nolock: cannot write 2048 bytes to LEB 788:86016 UBIFS error (pid 1044): ubifs_bg_wbufs_sync: cannot sync write-buffer, error -30 UBIFS warning (pid 1044): ubifs_ro_mode: switched to read-only mode, error -30 UBI error: ubi_io_write: error -5 while writing 2048 bytes to PEB 5817:26624, written 0 bytes UBI warning: ubi_eba_write_leb: failed to write data to PEB 5817 UBI: recover PEB 5817, move data to PEB 19408 UBI error: ubi_io_read: error -74 while reading 512 bytes from PEB 5817:512, read 512 bytes UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19408 UBI: try again UBI: recover PEB 5817, move data to PEB 19409 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19409 UBI: try again UBI: recover PEB 5817, move data to PEB 19410 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19410 UBI: try again UBI: recover PEB 5817, move data to PEB 19411 UBI error: ubi_io_write: read-only mode UBI warning: recover_peb: failed to write to PEB 19411 UBIFS error (pid 1047): ubifs_wbuf_sync_nolock: cannot write 2048 bytes to LEB 385:24576 UBIFS error (pid 1047): ubifs_bg_wbufs_sync: cannot sync write-buffer, error -30 UBIFS error (pid 1149): make_reservation: cannot reserve 160 bytes in jhead 1, error -30 UBIFS error (pid 1149): ubifs_write_inode: can't write inode 30709, error -30 UBIFS error (pid 1149): make_reservation: cannot reserve 160 bytes in jhead 1, error -30 UBIFS error (pid 1149): ubifs_write_inode: can't write inode 30710, error -30 UBIFS error (pid 1149): make_reservation: cannot reserve 160 bytes in jhead 1, error -30 UBIFS error (pid 1149): ubifs_write_inode: can't write inode 30698, error -30 UBIFS error (pid 1149): make_reservation: cannot reserve 160 bytes in jhead 1, error -30 UBIFS error (pid 1149): ubifs_write_inode: can't write inode 30711, error -30 I'd appreciate any hints on what can cause this. Is it a hardware problem, mtd layer problem or UBI problem ? Thanks a lot in advance. Felix.
