I guess this=20 message is not all that helpful - I have no idea what information I should= =20 have collected so it could be used for debugging. But at least now you know= =20 there is a problem at all. ;) After switching back to the old IDE driver, the system runs stable again fo= r=20 three days or so, so it's not a sudden coincidental hardware problem. Some details about my system (a Samsung R65 laptop, custom harddisk): $ lspci | grep IDE 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controlle= r=20 (rev 02) $ dmesg | grep "hd[ab]: " hda: HTS721010G9AT00, ATA DISK drive hdb: DV-W28EA, ATAPI CD/DVD-ROM drive hda: max request size: 512KiB hda: 195371568 sectors (100030 MB) w/7539KiB Cache, CHS=3D16383/255/63,=20 UDMA(100) hda: cache flushes supported hda: hda1 hda2 hda3 hdb: ATAPI 24X DVD-ROM DVD-R-RAM CD-R/RW drive, 1419kB Cache, UDMA(33) Kernel versions I tried (the problem appeared in both): =2D 2.6.21 with CK patchset =2D 2.6.21.5 with Gentoo patchset (http://dev.gentoo.org/~dsd/genpatches)=20 (gentoo-sources-2.6.21-r3 package in Gentoo's repository) There was no particularly heavy IDE load during the freezes.
