2.4.27-rc3 __alloc_pages: 3-order allocation failed (gfp=0x20/0)

Hi,

I got a lot such errors log when run dmesg and the rpogram cdda2wav seems stop extracting audio cds

Some others log like:

scsi : aborting command due to timeout : pid 3260, scsi0, channel 0, id 1, lun 0 0x00 00 00 00 00 00 scsi : aborting command due to timeout : pid 3260, scsi0, channel 0, id 1, lun 0 0x00 00 00 00 00 00 SCSI host 0 abort (pid 3260) timed out - resetting
SCSI bus is being reset for host 0 channel 0.
SCSI host 0 channel 0 reset (pid 3260) timed out - trying harder
SCSI bus is being reset for host 0 channel 0.
scsi : aborting command due to timeout : pid 3256, scsi0, channel 0, id 1, lun 0 0xbe 04 00 00 00 00 00 00 4b 10 00 00
hdd: lost interrupt

I use ide-scsi for ide cdrom as cdda2wav requires this. If I use normal ide-cd and use cdparanoia it works as normal.

What should I do to help debuging this problem?

Hi Steve,

The "3-order allocation failures" should not be a problem - its just the ide-scsi driver trying to allocate a big scatter-gather list of 8 pages, it fails then tries to allocate "smaller pieces" (4 pages then if that fails 1 page of memory).

Now the problem is the ide-scsi timeout's -- I really have not much of an idea what could be going wrong there.

Thank you for the reply.

I just found that if using cdda2wav but use it cooked_ctl interface (not the scsi one so I dont use ide-scsi any more) it works ; still until the last audio track it still report some error and hang , need to do Ctrl+C to stop it. However the last sound track is normal when play it. Use cdparanoia for both (ide-scsi or ide-cd) it works as normal.

I suspect bug in cdda2wav, or ide-scsi combination when readding cd text and info (I think cdparanoia does not read cd text). it may even be that my audio disc has some damage.
I will test with other audio cd today to see what happened.
