Partial output of dmesg
I dump IDE_STATUS_REG with e.g. 'printk("%s : recal_intr()
IDE_STATUS_REG=%02x\n",drive->name,stat)'
where stat was assigned as 'u8 stat=hwif->INB(IDE_STATUS_REG)'
It seems to me that the status is good until it tries to read the
partition table...
In fact, every time I do
sfdisk -R /dev/hdc
the next reading from compact flash (if ever does not get 'lost
interrupt) generates the message
hdc: status error: status=0x58 {...}

Output of dmesg on Gene-4312 board
On this board too, if dma is enabled it gets interrupts lost.
After initial trouble (maybe dma get automatically disabled?) all goes ok.
Disabling dma with the boot option ide=nodma all goes ok.
Disabling dma on the bios has no effect.
Marco, anything changed with the latest kernel, is the problem still there (2.6.22-rc7 or so)? Thanks. The problem is still there. On a SOM-4475 board (Bios versione 1.14), the Sandisk SDCFB-128 still doesn't go. (even with no dma support in the kernel, and with ide=nodma option) I cannot check now, if it is an hardware problem, bound to this specific board. Is this still a problem with 2.6.25-rc2?

Most recent kernel where this bug did *NOT* occur: none, already seen in 2.4.* kernel Distribution: Debian sarge *and* bootdisk made with uclibc Hardware Environment: VIA SOM-ETX (4475) and Gene-4312 Software Environment: shell Problem Description: Accessing the compact flash as /dev/hdc gives the message: hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown hdc: drive not ready for command [ the 'bad bit' is DataRequest ] and then, several hdc: lost interrupt Steps to reproduce: - Use a compact flash SanDisk SDCFB-128 Firmware revision HDX 2.15 (we used other compact flashes with the same hw ad sw for years with no trouble) - sfdisk -l /dev/hdc Other information: - sfdisk -R /dev/hdc does't block (no hdc: lost interrupt) - mounting an already existent vfat partition seems to be ok, no error messages, and copying a big file goes ok) - mounting an already existent ext2/ext3 partition does'nt function - enabling dma gives the message hdc: dma_timer_expiry: dma status == 0x21 hdc: DMA timeout error hdc: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown - booting with the irqpoll parameter does'nt stop the system, but the data on the compact flash are corrupted (after making and formatting a ext3 partition get message "allocating block in system zone" writing files on it } [ in the function irqreturn_t ide_intr (int irq, void *dev_id) in file drivers/ide/ide-io.c if (!drive_is_ready(drive)) -> is true ]
