| |
As I reported in bug 8036 in bugzilla.kernel.org,
Hardware Environment:
- 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)
It happens on both etx boards: - VIA SOM-ETX (4475) - Gene-4312
Doing the command sfdisk -R /dev/hdc
gives:
* * * ide1: start_request: current=0xc6ebe754 (rq->sect=0,block 0) hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown hdc: drive not ready for command ide1: start_request: current=0xc6ebe754 (rq->sect=0,block 0) hdc: do_special: 0x02 hdc: do_special: recalibrate ide1: start_request: current=0xc6ebe754 (rq->sect=0,block 0) hdc: reading: block=0 sectors=8, buffer = 0xc6cd40000 ide1: end_request: current=0xc6ebe754 * * *
the 'bad bit' in status error is DataRequest
doing sfdisk -l /dev/hdc
gives:
* * * ide1: start_request: current=0xc6ebecd4 (rq->sect=0,block 0) hdc: reading: block=0, sectors=32, buffer=0xc6f37000 hdc: lost interrupt hdc: lost interrupt [and so on several times] * * *
I have no knowledge of the internals of the linux kernel, but I'm a programmer and have both hardware and time to spend on solving this issue.
Thanks for suggestions...
