Summary: It failed some time when format harddisk of a large size on BF548-EZKIT
Details: In BF548-EZKIT, use "mke2fs" to format a ext2 partition. When the partition is larger than 30G, it fails some time, especially when format nearly the whole harddisk. Below is the log: register bfin atapi driver scsi0 : pata-bf54x ata1: PATA max UDMA/100 cmd 0x00000000 ctl 0xffc03800 bmdma 0x00000000 irq 68 ata1.00: ATA-6: TOSHIBA MK4032GAX, AD101A, max UDMA/100 ata1.00: 78140160 sectors, multi 16: LBA48 ata1.00: configured for UDMA/100 blk_queue_max_hw_segments: set to minimum 1 scsi 0:0:0:0: Direct-Access ATA TOSHIBA MK4032GA AD10 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 78140160 512-byte hardware sectors (40008 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 0:0:0:0: [sda] 78140160 512-byte hardware sectors (40008 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sd 0:0:0:0: [sda] Attached SCSI disk BF54x on-chip NAND FLash Controller Driver, Version 1.0 (c) 2007 Analog Devices, Inc. bf54x-nand bf54x-nand.0: page_size=256, data_width=8, wr_dly=3, rd_dly=3 NAND device: Manufacturer ID: 0x20, Chip ID: 0xda (ST Micro NAND 256MiB 3,3V 8-bit) Creating 2 MTD partitions on "NAND 256MiB 3,3V 8-bit": 0x00000000-0x00400000 : "Linux Kernel" 0x00400000-0x10000000 : "File System" rtc-bfin rtc-bfin: rtc core: registered rtc-bfin as rtc0 TCP cubic registered NET: Registered protocol family 1 NET: Registered protocol family 17 rtc-bfin rtc-bfin: setting the system clock to 2004-06-14 23:05:11 (1087254311) eth0: SMSC911x/921x identified at 0x24000000, IRQ: 175 eth0: SMSC911x MAC Address: 8a:10:f1:d6:21:05 eth0: link down IP-Config: Gateway not on directly connected network.

--- Vivi Li 2007-11-09 03:39:49 I can still reproduce this bug. Please set the partition size to a number that is close to the whole harddisk size and try again. I tried 3 times to format just after system bootup, and got one crash. Below is part of log of my partion, and set total cylinder numbers to 4800. ----------------------------------- Command (m for help): p Command action e extended p primary partition (1-4) Partition number (1-4): 1 First cylinder (1-4864, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-4864, default 4864): +4800
--- Sonic Zhang 2007-11-26 03:56:12 Fixed. Return properly IRQ status.
--- Vivi Li 2007-11-28 21:48:57 I test it with total cylinder numbers 4800, it will still fail sometimes with following log. Below is the log: #### root:~> fdisk /dev/sda The number of cylinders for this disk is set to 4864. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Command action e extended p primary partition (1-4) Partition number (1-4): 1 First cylinder (1-4864, default 1): Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-4864, default 4864): 4800 Command (m for help): w The partition table has been altered!

--- Sonic Zhang 2007-12-26 05:33:42 Fixed by covering all possible ATAPI interrupt sources when checking dma status.
--- Vivi Li 2008-01-08 03:01:18 I can still see this bug on test machine.
--- Robin Getz 2008-04-15 07:02:30 Increase the priority since other people are seeing this on other platforms still.
--- Sonic Zhang 2008-04-18 04:04:04 Fixed. Implement bfin ata interrupt handler to avoid "irq 68 nobody cared". Return IRQ_HANDLED when bfin ata device is busy.
--- Vivi Li 2008-07-28 00:14:40 OK now. Close it. Thanks!
