Subject: [OOPS] Oops with kernel 2.6.9-rc2

Dear people,

Yesterday night, I was running my own self compiled kernel 2.6.9-rc2,
without any patches applied and, while I had my computer left unattended
for some moments, I saw that it generated two Oopsen in a row.

BTW, I was excited to use 2.6.9-rc2 because it included the 8 byte-fix for
USB urb's, which is needed for my desktop to cooperate with my USB Drive.

I'm attaching the decoded Oops through ksymoops. I'm using a Debian testing
machine with a Duron 600MHz processor, an Asus A7V motherboard and 386MB of
memory. The kernel is not tainted. I used GCC 3.3.4 to compile the kernel;
gcc --version says: gcc (GCC) 3.3.4 (Debian 1:3.3.4-6sarge1).

Since the decoded Oops mentioned things related to filesystems, I became
scared, with fear of data corruption.

Please let me know if any further details are necessary about the
situation.


Thanks, Rog?rio Brito.

Were you using a cdrom at that time? If so, this will probably fix it:

Yes, I think that I was. Today I got another amount of Oopsen. I will
try the patch right now and report back my results.

Thank you very much, Rog?rio Brito.

I've been using 2.6.9-rc2 with the patch and it's working well - no oops with
cdrom use now.

Just as a feedback that I promised, it's working correctly now with the
patch applied. It seems that the problem was indeed caused by accessing
CDs.


Thanks, Rog?rio.
