DOH! ata_alloc_request failed!

[Mars G. Miro]

Greetz Søren, List!

  I had about 6 directories  (~1G/dir) I had to remove (chflags -R
noschg && rm -rf), then I encountered these:

Later on:

Then there was a directory that wasn't deleted completely so I had to
chflags and rm -rf it.

A few people also experienced it in 6.0-RC1 last Nov:

>From that thread, somebody suggested something and mine gives:
root at marsz:/home/jails# sysctl -a | grep ^ata
ata_composit:    376,        0,      0,   1300,  1544911
ata_request:     336,        0,      0,   2376,  4969864

My system is RELENG_6 as of Apr 04 on amd64:
FreeBSD marsz.XXXXXXXXXX 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #0: Tue
Apr  4 13:23:43 PHT 2006    
root at XXXXXXXXXX:/usr/obj/usr/src/sys/MARSZ  amd64

It is configured in ATA-RAID1 using a built-in:
atapci0: <Promise PDC20378 SATA150 controller> port
0xec00-0xec3f,0xdc00-0xdc0f,0xcc00-0xcc7f mem
0xfdc00000-0xfdc00fff,0xfdb00000-0xfdb1ffff irq 18 a
t device 8.0 on pci0

Though I have not crashed or anything, just wondering if it means
anything at all. I do recall back in 5.4X that I crashed doing similar
things and I had to manual-fsck in single user mode (bgfsck wouldnt
work). This gives 6.X a ++ ;-)

Thanks and FYI ;-)


cheers
