I also just ran into the ext2 bug:

Feb 25 06:27:05 morpheus kernel: EXT2-fs error (device ide0(3,1)):
ext2_readdir:
directory #881700 contains a hole at offset 0
Feb 25 06:27:05 morpheus kernel: Remounting filesystem read-only

I had been running 2.4.1 before upgrading to 2.4.2. My machine had been
up with 2.4.1 for 13 days, then i added a system fan, then it was up for
another 8 days after that with no problems.

Up with 2.4.2 for about a day and I ran into the above ext2 error. I also
have the VIA Apollo chipset:

00:07.1 IDE interface: VIA Technologies, Inc. VT82C586 IDE [Apollo] (rev 10) (prog-if 8a [Master SecP PriP])
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 32 set
Region 4: I/O ports at d000 [size=16]
Capabilities: [c0] Power Management version 2
Flags: PMEClk- AuxPwr- DSI- D1- D2- PME-
Status: D0 PME-Enable- DSel=0 DScale=0 PME-

Also, during boot phase I had been manually running:

/sbin/hdparm -d1 /dev/hda

To turn on DMA on my primary disk since the 2.2.x series didn't turn this
on by default. /dev/hda is a Western Digital:

Feb 25 12:35:37 morpheus kernel: hda: WDC WD273BA, ATA DISK drive
Feb 25 12:35:37 morpheus kernel: ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Feb 25 12:35:37 morpheus kernel: hda: 53464320 sectors (27374 MB) w/1961KiB Cache, CHS=3328/255/63


Let me know if there is any other information I can provide. I also have
a notebook which as been running 2.4.2 without trouble for a few days.
This notebook has an Intel IDE controller. Seems to me like this is a VIA
Apollo bug...... Thanks.
