I use Slackware9.1, Kernel 2.6.3, on an HP Omnibook XE3GF, chipset Intel,
QSI CD-ROM SCR-242
When I try to access files on some cd-roms i got the following error:
Code:
file.name: ERROR: cannot read `file.name' (Input/output error)
The last lines of my dmesg read:
Code:
ISO 9660 Extensions: Microsoft Joliet Level 3
ISOFS: changing to secondary root
attempt to access beyond end of device
hdc: rw=0, want=478432, limit=52996
Buffer I/O error on device hdc, logical block 119607
When I say I get this error on "some" cds, I mean it's really random. It's not related to media size, file system, burned cds VS original cds.
None of this happens in kernel 2.4.X, so I think it's related to the new ide drivers of kernel 2.6.X.
I'll paste some more info of my SlackBox:

I already tried searching LQ forums and Google, but even if somebody else reported having the same problem, it was on a 2.6.X-test and anyway nobody seems to have tracked the bug/problem.
Thanks in advance and sorry for the long post.
