I'm open to suggestions of what to try, patches etc.
I also have some additional information: it didn't actually hang with
2.4.20-pre7-ac2. It recovered after some minutes, just after I had sent
the last message. But the disk (hdd - the problematic mwdma Seagate) was
put offline so the problem persists, it just has a little different
form. The kernel decided that the disk is not accessible, that gave
errors to ext3 and ext3 survived too, giving IO errors and empty
directories to the user (and many errors in the syslog). The disk still
works fine in 2.4.18. dmesg:
hdd: dma_timer_expiry: dma status == 0x61
hda: dma_timer_expiry: dma status == 0x61
hdd: timeout waiting for DMA
hdd: timeout waiting for DMA
hdd: (__ide_dma_test_irq) called while not waiting
hdd: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hdd: drive not ready for command
hdd: status timeout: status=0xd0 { Busy }
hdc: DMA disabled

and so on, later also ext3 errors as a result.
