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...
