Dear Debian,
So, reportbug forgot to inlcude the majority of the report:
USB pendrive fails when syncing file systems (works OK with big sequential
copies) with "reset high speed USB device" and "device descriptor read/64,
error -110" and "sd 0:0:0:0: scsi: Device offlined - not ready after error
recovery" and "scsi 0:0:0:0: rejecting I/O to dead device"
Laptop is HP NX 6125, Pendrive is A-DATA PD7:
00:13.0 0c03: 1002:4374 (prog-if 10 [OHCI])
00:13.1 0c03: 1002:4375 (prog-if 10 [OHCI])
00:13.2 0c03: 1002:4373 (prog-if 20 [EHCI])
Bus 003 Device 013: ID 090c:1000 Feiya Technology Corp. Memory Bar
sd 4:0:0:0: [sda] 4046848 512-byte hardware sectors (2072 MB)
sd 4:0:0:0: [sda] Assuming drive cache: write through
A workaround is to issue:
echo "64" >/sys/block/sda/device/max_sectors
but that slows down copying to 2.6.18 level (which had no such issue).
Without the workaround, I borked my FAT (fat_get_cluster: invalid
cluster chain (i_pos 0), FAT: Filesystem panic (dev sda1)) and ended up
having files filled with zeroes. Severe data loss, could be a problem when
kernel gets into Etch.
Seems to affect only high-speed USB HUB (only EHCI?) +Pendrive.
Google is full of "reset high speed USB device" with many different USB
stuff - from external HDDs to network cards.
